BUFFETT: You now have the four largest companies, by market value, in the US — a $30 trillion market — that essentially don’t need any net tangible assets. If you go back many years and look to the largest companies, it would be AT&T, General Motors and Exxon Mobil. These companies required a lot of capital to produce earnings. American industry has gotten incredibly more profitable, in aggregate, over the past 20-30 years. Look at the return on the S&P 500, the earnings as a percent of net tangible assets, and the rest is just, you know, if you buy a company that has a million dollars worth of net worth and you pay a billion for it, it still only had the million dollars of net worth. I mean you just paid more for it. So, the basic profitability of the company is huge, even though your investment may be at a significantly higher price. If you look at the earnings on tangible net worth of the S&P 500 and compare it to 20 years ago, it is amazing. And that is really due to the fact that this has become somewhat, you could call it an asset-light economy. Those four companies now comprise close to 10% of the market value of the entire publicly traded corporate America and don’t need any money. They will earn even more money with the tax rate going down.
