Kindness as in cooperation versus meanness as defection, and you're correct.
Turns out being mean helps ensure cooperation, sometimes, though, when people would rather defect if left to it. Game theory is useful for finding which way large scale interactions/large numbers of interactions trend to on average.
So, here's something that could maybe fix a lot of the problems. Get ranked voting, proportional representation, mandatory voting/mail-ballot/national holiday on election day, and campaign finance reform. There's multiple ways to go about that last one, I'm not sure which one is best. Which of course means I'm talking out of my ass, but I see two primary ways; either make it so everyone has about the same amount they're allowed to donate (maybe up to five thousand dollars from an individual, and if corporations are people, only 5000 dollars from them, as well(parent company, not all their little subdivisions), and no MNCs get to be involved in elections), with a 'stipend' of money that comes from taxes (there's almost always room for another 5 or 6% on the top brackets; it was at 79+% at one point and economy was fine; it's nowhere near that high now, though obviously technology circumstances are different). Maybe $10-$100 a person per race. Or something like that.
Alternatively, make it so that candidates receive money from a central pool; campaigns all receive the same amount of financing, paid for by tax money. Only issue here is that when there's a lot of candidates, either it starts getting real expensive as each gets the starting flat amount, or each campaign starts having very little to work with as funds get split too many ways. One way to avert this would be having entry requirements to show that you're serious/have a chance, but that carries a number of it's own problems as one can probably imagine.
Of course, one of the big issues with being able to reign in big companies is competitive taxation. They have the right to leave, afaik, and if they feel like they can get more favorable taxation/regulation policy elsewhere, it's entirely possible they will. Speaking of regulations, in terms of economics and gov't interacting with business, fewer unnecessary regulations would really help matters, I suspect. Small business costs from regulations are often significantly higher than large businesses. Closing tax loopholes and preventing the whole 'taxes rise proportional to income until there's a stack overflow error and you no longer pay them, just your tax lawyer' issue would probably help the budget, at least.
@MrRoboto75 Unfortunately, most terrible business decisions are easily made reasonable when you consider them in the light of the corporate god: short-term quarterly profits.
I really do think that if businesses/corporations thought in the long-term for profit, and were informed/intelligent, that they would behave much better. In the age of information, bad PR can be devastating, while good PR can be an extremely worthwhile investment. Look at how they tend to interact with charities, for example. Likewise, cooperation tends to be more beneficial for everyone in the long run than defection (like overworking your employees; turns out you're actually less productive if you're doing sustained 50 hour work weeks than if you just do 40 hour work weeks with a 50 hour only if there's a serious deadline coming up or the like). Same with things like not ruining local infrastructure/water supply/the environment. This is where your business operates. But, of course, especially in the Celebrity CEO era, as long as they can come up with plenty, they don't care if the business goes under >.>
