When people get upset about well-to-do people not paying their "fair share" -- aside from missing the obvious fact that they carry the vast majority of the tax burden, they miss the whole point of the role of high income in a Capitalistic Free Enterprize System.
People have an emotional reaction to the big houses, fancy cars, and other material perks of the wealthy. That stuff is peanuts. If you took all of that stuff away and redistributed the proceeds from the sales, it would be just a drop in the bucket toward satisfying the goals of progressive tax proponents.
The real money is that which they invest. The major point missed is that the wealth of the well-to-do is a key cog in the engine of our econmony--including job creation. The vast majority of the assets of the well-to-do are actually already "donated" -- given to others. Even when they get interest back on their wealth allocations, they just give it away again (keeping just a small percentage for personal perks).
They aren't putting their money in a mattress. They are literally giving it to others who start up new companies, expand existing companies, build hospitals, fund municiple projects, build libraries, provide capital for construction companies so they have the front-end capital to take on construction of buildings, bridges, highways, etc.
And their money is also provided to funds from which lower income people borrow to buy cars and houses. And it's done much more efficiently than the government mode of redistribution of income.
That's what Capitalism and Free Enterprize is all about. Now, the proponents of high corporate taxes as well as excessive personal income taxes for the wealthy would unwittingly induce the unintended consequences of choking of this whole process (some progressives, socialsts and Marxists would choke intentionally). This is the process by which this country developed its technology and high standard of life over generations. Socialist countries actually benefitted from the creativity that evolved naturally in the Free Enterprize environment of the U.S. The U.S. Capitalists put up the seed Capital. Sure, Canada may have low cost medicine, reaping the fruits of R&D investment capital in the U.S.
If the government would get out of the way and quit the ever increasing confiscation of wealth, we could continue on an established path of success and excellence. The government's redistribution of wealth is no where near as successful in resolving the problems of the poor as the the wealthy are by investing the vast majority of their wealth in projects leading to job creation.
And the thousands of investors of discretionary money make far better decisions about where money should be directed as compared to government beauracracy. People like Bill Gates manage their money much better--to take away another couple of billion of his wealth is to simply penalize all of those who would have benefitted. And if you don't like Bill's allocation of his wealth, at least there are many many more institutions taking varieties of approaches. Free Enterprize takes the best of the myriad of approches and sustains the ones that work.
God bless the rich, the entrepreneurs, and the innovators. May liberals, progressives, socialists, and Marxists be unsuccessful in their attempts to hijack the process.
