From Ron Pisaturo:
When Obama speaks of the government ‘investing’, he is of course perverting the meaning of the word; he is really spending wealth confiscated from others. But there is a sinister way in which his use of the word ‘investing’ is revealing and apt: the government is ‘investing’ in contrast to ‘lending’. When a creditor makes a loan, the creditor obtains a promise to repay the loan with interest; in contrast, when an investor makes an investment, the investor obtains ownership and a share of the profits.
Since, according to Obama, the government ‘invests’ in you—by paying for your schooling, etc.—the government expects not a repayment of a loan to you, but rather a share of the profits in you.
