On the revenue front, the U.S. is also in the lead in terms of receipts and total deficit. The deficit alone could buy 86 companies in the S&P.
That revenue tops each individual company in the S&P 500, and by a lot. You'd have to combine the annual sales of the top 26 companies to match it. That's everything from Wal-Mart to Wells Fargo.
By budget line, the Agriculture Department gets about $150 billion, putting it in line with auto companies like General Motors and Ford in revenue. The Fish and Wildlife Service, which is within the Department of the Interior, has a budget request of around $2.9 billion, making it about the size of Urban Outfitters by market cap.
As a lame duck president, Obama doesn't have much to lose and could accomplish more if he can find allies in Congress to compromise on the more moderate proposals.
Last week, it was announced that Obama would seek a $10-per-barrel tax on oil in order to raise $20 billion to fund research into alternative energy sources. With crude hovering around $30 a barrel, the extra tax could take a serious bite out of producers' incentives to drill.
If the $10-a-barrel tax had been enacted in 2015, that would bring in about $34 billion in additional revenue for the government (assuming that tax didn't force any producers to cut output), based on production figures from the Energy Information Administration. The government could buy the bottom 13 companies in the S&P with that money, a group that includes GameStop and Chesapeake Energy.
Four federal agencies have double-digit portions of the overall expenditure budget. The Department of Defense is in the news a lot for getting a sizable chunk of the budget, but it's actually smaller than Health and Human Services, Social Security and the Department of the Treasury. Its $575 billion budget (based on 2016 projections) buys a lot of F-15s, but it could also buy any company on the S&P, or the hundred smallest.
