Politicians will always spend every penny of tax raised and whatever else they can get away with.

To the best of my knowledge, there has never been a monetary union, putting out a fiat currency, composed of independent states.

Self-interest is not myopic selfishness. It is whatever it is that interests the participants, whatever they value, whatever goals they pursue. The scientist seeking to advance the frontiers of his discipline, the missionary seeking to convert infidels to the true faith, the philanthropist seeking to bring comfort to the needy - all are pursuing their interests, as they see them, as they judge them by their own values.

Nobody spends somebody else's money as carefully as he spends his own. Nobody uses somebody else's resources as carefully as he uses his own. So if you want efficiency and effectiveness, if you want knowledge to be properly utilized, you have to do it through the means of private property.

The preservation of liberty, not the promotion of efficiency, is the primary justification for private property. Efficiency is a happy, though not accidental, by-product - and a most important by-product because liberty could not have survived if it had not also produced affluence.

Freedom is a rare and delicate plant. Our minds tell us, and history confirms, that the great threat to freedom is the concentration of power.

If the US government spends 40 percent of the nation's income, as it does through either borrowing or taxes, that income is not available for people to spend. The deficit is an indirect method of taxation. Of course, politicians prefer to borrow instead of tax because then someone down the road has to deal with the consequences.
