P.S.

Another thing to remember is that government expenses are often investments. This doesn't only apply to health, education, law enforcement, and transportation infrastructure but also to social security. If people think they'll be left penniless at retirement, they'll spend less and save more. Borrowing to finance investment is a wise policy when the resulting growth can pay for the interest and then some, even if it means a growing debt.

If you invest well, leveraging your investment is exactly what you should do.
