Any economist worth their salt knows that taxes may or may not inhibit economic growth. Taxes invested in infrastructure, security, and education may actually increase growth long term. Taxes wasted on corruption will most definitely hurt growth. Property taxes also encourage people to put properties to work, inheritance taxes encourage more dynamism between the generations (discourage old money aristocracy), and so on. Overly harsh taxes on the rich will also encourage avoidance (honest or dishonesty) and migration (negotiate your own rate with a swiss canton), while regressive taxes on the poor will lead to riots and revolts.

Societies are complex systems and managing them efficiently is actually (gasp) quite difficult.
