Here are some great excerpts:
... We may think of taxes as just a source of government revenue. But tax rates are a big political statement on the left, whether they bring in any revenue or not.
For more than 80 years, the political left has opposed what they call "tax cuts for the rich." But big cuts in very high tax rates ended up bringing in more revenue to the government in the Coolidge, Kennedy, Reagan and Bush 43 administrations. This included more-- repeat, more-- tax revenue from people in the highest income brackets than before.
... After all, "the rich" paid that larger sum of taxes only because their incomes had risen. Their paying a higher share of all taxes doesn't matter to the "progressives," who see high tax rates as a way to take a bigger bite out of the incomes of higher-income people, not just provide more revenue to the government.
Tax rates are meant to make an ideological statement and promote class-warfare politics, not just bring in revenue.
....Internal Revenue Service data show that the income of people who were in the lowest income tax bracket in 1996 rose by 91 percent by 2005. But people in the "top one percent" had their incomes drop by 26 percent in those same years.
There is nothing complicated about this. Most people simply start at the bottom when they are young and their pay rises as they get more experience. Most people in the top one percent are there for only a single year when they happen to have a spike in income. They too are not an enduring class.
