One of the commonest things to do with savings is to lend them to some government. In view of the fact that the bulk of the expenditure of most civilized governments consists in payments for past wars and preparation for future wars, the man who lends his money to a government is in the same position as the bad men in Shakespeare who hire murderers. The net result of the man’s economical habits is to increase the armed forces of the State to which he lends his savings. Obviously it would be better if he spent the money, even if he spent it on drink or gambling.
