I didn't say higher taxes prevent prosperity. What I said is that taxes alter the behavior of corporations and how and where they deploy their resources.Tax policy has become a tool of centralized economic planning, using incentives and disincentives to steer companies and individuals into behaviors the government feels are the most beneficial to the economy. That works fine if countries existed in isolation since governments have no competition to their policies. However in a global economy capital and resources are mobile. If a corporation doesn't like the tax policy of a country or feels it can or needs to gain a competitive cost advantage by deploying their resources elsewhere then that's exactly what they'll do. If a country wants to be the recipient of those resources then they have to compete for them, the same as how corporations have to compete for revenue and profits.
