Lord Bucket, I find it odd, being that you are in such favor for any means necessary to reduce work, that your first instinct is to replace a generally fairer tax practice with a less fair one, when you could just automate the process?
I mean, it took me 30 minutes to do my tax this year. Just because the US government is really crap at administering is progressive tax system, it doesn't mean that its impossible to administer a progressive tax system well. Australia has an (optional) Automated electronic tax system, and a single tax payment point per year (apart from council rates, I guess), the state government gets their cut from the federal government. You just put in your tax file number (social security number equivalent, basically?), put in a tax statement from any jobs you've had, fill out any fields for your assets, other income, dependents etc and then lodge it online. Businesses are being increasingly integrated into the system, both for ease of use and government checks (for example, they monitor transactions from small businesses, and can have their servers farms etc automatically detect if you under report your income and so on) Give it a few years and you probably won't even need to be inputting much of your data at all, the government will already know much of what it needs to, you'll just review it and accept.
Now, to be fair I don't have a very complex set of assets or income, just work, some interest on money, plus deductions from health insurance. However, even then if you are adequately prepared it'll only take you a pretty short time, not the 20 hour average that your statistic mentioned for the US system
Anyway, this is just another nitpicking point, not really adding anything to the work reduction theme of the thread, but since you've spent the last 3 pages responding to it I figured i'd post it here.
However, if I may, I'd like to call you out on those figures you gave for the sewer system upgrades. San Antonio, for example, is looking to spend $1 billion on a sewer system for 1 million people. That's 100 bucks a person. Its an equivalent cost to a septic tank for everyone.
also also, there's probably on the order of upward of 1 trillion man hours (of just work, not including peoples spare time) per year in the USA anyway, 6 billion is a pretty small drop in the bucket. Infact, the collective hours lived by people in the USA every year is 2.77 trillion, and tax takes up .216% of this time.
