In one of the threads referenced above, there’s a lingering question (and the tone persists in this thread) about why the rich should pay more in taxes than the poor.
The answer is, the rich benefit more. By virtue of being rich, they’ve demonstrated that they benefit more from the security, ease of commerce, public education, etc
Any honest accounting system must consider that wealthy individuals benefit not only directly from police security, roads, etc, etc, but indirectly as well. Any underling who creates income for a company in excess of his or her wages has been enabled to do so by tax-supported society, and therefore their benefit to society is also the employer’s. If that underling couldn’t get to work because there were no roads, or couldn’t leave home because their family would be unsafe, or couldn’t perform the job because they hadn’t the schooling to read and write, well, then that surplus wouldn’t exist for the employer.
Multiply that by the countless benefits a governed society provides, and it’s easy to see how the richer an individual is, the more of a bargain his/her tax bill actually is.
