Sigh.
Investing in current stock does not create jobs. If I buy 1000 shares of Coca-Cola or GEICO stock or BNSF stock, it will not cause any of those companies to hire a single employee, because I am not buying the stock from the companies, I am buying the stock from someone who bought it earlier and sold it because they needed the money, or thought that some other stock was a better investment.
Warren Buffett can be described in many ways, but to call him a "hard core leftist" is utterly ridiculous. The people he benefits the most and always have benefited the most are those who own shares in Berkshire Hathaway, which come in two sizes, one goes for $131,916 per share and $88.08 per share.
The beta on BRK-B is .29, which means that it is not a very risky stock. A beta of 1.0 is average.
The term "ovarian lottery" is one Buffett uses rather often, I do not know whether he invented it, and I see that it could apply to anyone who is born to some degree. He uses it to refer to those who are born to parents who educate their children well, pass along genes for various talents and perhaps an inheritance as well.
I can't say I agree with him on every issue, but I do find him to be a nicer guy than Carl Icahn, Jack Welsh or Mitt Romney. He entreats the super rich to pass on their money to the less fortunate,and does not seem to have such a large ego that he feels a need to not collaborate with Bill Gates on his campaign to eradicate Guinea worm, malaria, bilharzia and other nasty tropical diseases. Doing this creates jobs as well, though perhaps not as many as in the US as in Africa and tropical countries,
