This is the part people are bothered by.
Regardless of why, billionaires should never be paying $0 in federal income taxes. Our tax code and the people finding loopholes in it should not do this.
Executives should not be able to be "unpaid" for years because they're getting tax advantaged stock deals.
Nobody should be able to have that much wealth and have a year with no taxes.
If you are the human at the end of the line of ownership that ultimately benefits from assets, you should be charged ordinary income as you extract from those assets.
The only people who should owe $0 in federal taxes are those earning less than a full time minimum wage salary during that tax year, with no exceptions for folks who magically seem to find millions of dollars to spend during a year that they "earned" $0.
> a year with no taxes
These are two very different things, and the former does not imply the latter.
His wealth growth of $24.3bn is untaxed through those years, he presumably left those assets in Berkshire Hathaway where he'd personally not generate a tax bill for them. Eventually Buffet, or more likely his inheritors, will sell the Berkshire Hathaway assets, and should pay a monumental tax bill on them.
