Bloomberg's Zachary R. Mider looks into how much the Waltons, the family that owns Walmart, pay in taxes. The answers are positively Romneyesque:

America’s richest family, worth more than $100 billion, has exploited a variety of legal loopholes to avoid the estate tax, according to court records and Internal Revenue Service filings obtained through public-records requests. The Waltons’ example highlights how billionaires deftly bypass a tax intended to make sure that the nation’s wealthiest contribute their share to government rather than perpetuate dynastic wealth, a notion of fairness voiced by supporters of the estate tax like Warren Buffett and William Gates Sr.

Estate and gift taxes raised only about $14 billion last year. That’s about 1 percent of the $1.2 trillion passed down in America each year, mostly by the very rich, former Treasury Secretary Lawrence Summers estimated in a December blog post on Reuters.com. The contrast suggests “our estate tax system is broken,” he wrote.

I'll say it: Nobody needs a hundred billion dollars. Nobody is worth a hundred billion dollars. There should be no way on earth to earn a hundred billion dollars. Nobody works a hundred billion dollars harder than someone who makes minimum wage. It's impossible. It's wrong. It's evil.
