I have trouble finding an example of the government running something more effectively than private enterprise.
People in certain governmental institutions are very motivated at fulfilling their roles, for example the armed forces in some countries take a lot of pride in keeping themselves in the best shape and making the best of their resources, however much it is, not out of any monetary desire. Emergency services also often share this sort of work ethic. There are many ways to instill this sort of ethic in people, be it through material goal, personal standards, or conceptual motivations.
This is a question of how well can both adapt to changing situations. Of which when we're talking about how a private and governmental institution can change, it largely depends on the people in charge. For example, very bad banking practices led to the near fall of several large banks. This evidently did not change as Barclays who was bailed out was found to be fixing their loan rates. And not only this, seemed to be doing so in response to other banks doing the same thing. There are instances where private industry can't adapt due to its leadership or extenuating circumstances. Governments too can suffer from this, though of course both have shown that they change when circumstances require.
When private enterprise does poorly, it's usually because there are regulations put in place that prevent them from increasing efficiency.
Well no. When private enterprises do poorly it is commonly due to incompetence or laziness. Do you know how many people with no business experience opens up a business? Just take a look at random kickstarters page and be amazed at just how poorly some of these ideas are thought out.
An example of this is the private health care system (I just opened a big can of worms, didn't I? This is just a small example, I don't want this to become the focus of the discussion). People claim the government can operate it better than business. But getting rid of a few simple government regulations could drastically reduce costs by increasing competition. One such thing is the inability to purchase out-of-state health insurance. If I, as someone living in New York State, were allowed to purchase health insurance from a company in Pennsylvania, imagine how costs could be driven down; the health insurance companies in New York that had cornered the market would have tons of new businesses to compete against, and the best way to attract costumers is to lower prices or improve the quality of service. So this is an example of government rules preventing the best effects of free trade from occurring (because in this case the free trade is being inhibited).
I really don't know that much about health care systems to speak very much about it. Other members of this forum seem to know much more. I will address the regulations though. I admit that there can be, and are, very poorly thought out regulations. That being said, these regulations are there for the sole reason that people demanded that they exist, and most of them seem to exist for plausible reasons.
The main question is whether inhibiting the market in a certain way will provide benefits that justify it. And in terms of insurance, this seems to be the case.
As far as I know, people care a lot about insurance, so much so that they often go to court over it. The regulation of what an insurance company can and can't do seems to be justified in that the states have the power and not the federal government (unless of course you think justice counts as inhibitors of the free market). If it was the federal government making the laws, there would probably be a national market for it. This however does overlook that each state has very different demands that is asked of the insurers, and different regulations that arise from this. These demands for better or worse have been asked to be mandatory. Many of these are restrictive, for example making everyone buy health or any other insurance of some kind. For laws to exist like these there must be support for it, I don't think any insurance body would offer this select state insurance if its people wanted insurance agencies to provide such a demanding and risky service. And if they don't, then the free market would have clearly over-looked them as their ideal desire of what insurance they want won't be available. They'd have to settle for sloppy seconds.
It's very hard for me to make a solid argument when our current system does not usually support 100% free trade policies. What I'm getting from this debate is that I'm trying to argue for free trade - "let private enterprise do their thing" -, and you are arguing against it - "the government can do some things better than business". But I can come up with no perfect examples to support my claim, because 100% free trade hasn't existed in the US. As such, I have no practical examples, only "what if"s.
We could look at places where regulation exists minimally, or indeed are not enforced at all. There are certain places in this world where regulations can be waived when you give money to a certain individual. Third world countries are often like this. The black market is one other such entity, though I'm sure you're aware of the danger the products or services themselves can present even without any of the legal ramifications.
I agree that if the government can do something better than business, they should. The problem is I'm having trouble finding a good example of this (outside of things like the military- but who knows, maybe private enterprise could do that better too? I haven't examined the issue at any depth to tell). I support free trade only because it seems to have the best results. If you can prove to me that government run programs would have better results than private programs for the same thing, I would support the government.
We both agree that the main aim is the general good of the entire population. We only differ on how this can be achieved. And I guess this overlooks an issue with government. It's slow because many people have asked it to be such. We've rather it be accurate and careful with its workings than the other way around and absorbing the mistakes for the efficiencies that will arise. Political and economic stability is its real job.
So if voters opt that the government take the role of a certain industry, it should be sending a signal about how people wish said industry to be, yes?
As for the armed forces, you really don't want it to be owned by certain members of society and excluding others. And of course, you really don't want any foreign investment money going into it if you want to keep sovereignty. Motivation to do a better job comes in many paths, some militaries make the best with what they can and almost all members are invested in the institution as a whole. While people's material self interest in important, appealing to only this one facet of people's motivational set isn't reliable nor efficient. For most people, a whole plethora of priorities take precedent over making more money than you need to live comfortable for the foreseeable future. Soldiers, emergency response personnel, and doctors in some countries have institutions that tap into these other motivational facets as well as their material self interest to achieve similar results.
We see private industry doing this today as well. Not only are they giving people money to do their job, they want to make their employees to be invest in their place of employment in the same way as these other professions that the government employs.
