Buffet objects to paying at a lower tax rate than the middle class. He also refutes the notions that higher taxes discourage investment or job growth. From "Stop Coddling The Super Rich":
While the poor and middle class fight for us in Afghanistan, and while most Americans struggle to make ends meet, we mega-rich continue to get our extraordinary tax breaks...
...These and other blessings are showered upon us by legislators in Washington who feel compelled to protect us, much as if we were spotted owls or some other endangered species. It’s nice to have friends in high places.
...The mega-rich pay income taxes at a rate of 15 percent on most of their earnings but pay practically nothing in payroll taxes. It’s a different story for the middle class: typically, they fall into the 15 percent and 25 percent income tax brackets, and then are hit with heavy payroll taxes to boot.
...I have worked with investors for 60 years and I have yet to see anyone — not even when capital gains rates were 39.9 percent in 1976-77 — shy away from a sensible investment because of the tax rate on the potential gain. People invest to make money, and potential taxes have never scared them off. And to those who argue that higher rates hurt job creation, I would note that a net of nearly 40 million jobs were added between 1980 and 2000. You know what’s happened since then: lower tax rates and far lower job creation.
...for those making more than $1 million — there were 236,883 such households in 2009 — I would raise rates immediately on taxable income in excess of $1 million, including, of course, dividends and capital gains. And for those who make $10 million or more — there were 8,274 in 2009 — I would suggest an additional increase in rate.
My friends and I have been coddled long enough by a billionaire-friendly Congress. It’s time for our government to get serious about shared sacrifice.
