[quote name='UncleBob']It's a strange, new world where 50% of earners pay for 95% of the bill and that's "fair".[/QUOTE]
Because the better off should carry more of the country's burden.
If people don't care about community and helping others, and are just out for themselves and getting a much as they can, then humans are no better than other animals only concerned with survival. Worse since they're concerned with material items and status--not just survival.
Unfortunately, that's the reality of human nature and we're inherently hedonistic. There would be much less social programming, no military really etc. if it was all dependent on donations and charity--so some form of tax system is required.
Given the American Dream as the foundation of our country, and it's notion that anyone can succeed through hardwork. Those who have succeeded should pay higher percentages of their income to allow the lower and middle classes to pay lower percentages as they're trying to pull themselves up.
And I don't say that as a college student making nothing etc.--I'm already in the second highest income bracket in that silly chart you posted a couple pages back, and would be into the highest if I married my current girlfriend and we filed jointly.
I'm perfectly fine paying a higher tax bracket to help others as I was helped by public schools and public universities, make use of public parks, benefit from the safety of having a strong military, police forces, fire departments etc. I'm willing to pay a larger share of that to help out those who can't put as large a percentage of their income into the pool. And I'm fine paying for social programs to help out the disadvantage and improve their chances of getting by and hopefully pulling themselves up.
[quote name='UncleBob']All I did was point out that the rich pay more in taxes (contrary to what some post/believe) and that the idea that they aren't paying their "fair share", when they're paying far beyond what anyone else is paying is ludicrous.[/QUOTE]
And as Myke already pointed out, far less than they were prior to Reagan's dumb ass changes. And the debut was much smaller and the economy was growing rapidly through many of those preceding decades when the highest bracket was 70% or something. The fact of the matter is that we just need more tax brackets for the upper class.
It's just silly to stop at $370K, and that person pays the same percentage as a person who makes millions or billions. Tax the uber rich more, its not good to have so much of the wealth concentrated in the top few percent of a population.
