taxation is the system that maintains peace and stability and international commerce that enabled the success of amazon. But they are a product of the peace, stability and globalization of commerce - taxing them more doesn't increase the ease with which new amazons could come about. Taxes are fungible, and gets spent on things that may not help, so a company (or individual for that matter) would not just blindly pay more tax, and hope for the best.
Gov't should firstly set out the policies that they think will allow for the growth of more amazons and such, fund it, _then_ tax the population after the fact. Because tax dollars obtained without any difficulty is often merely just wasted in gov't.
