Bloomberg, 33 other billionaires pledge to give away half their wealth

The New York Post reports:

More than 30 U.S. billionaires pledged on Wednesday to give away at least 50 percent of their wealth to charity as part of a campaign by investor Warren Buffett and Microsoft founder Bill Gates.

But, Uncle Sam isn't going to get it. Warren and gang want you to pay an inheritance tax: while they avoid through charities they control.
