Government Policies and their Impact on Business

Whether we like it or not, governments and their policies have a big impact on our business. Dornubari uses the example of African governments' taxation of the tech sector as a brake on business and a cause of brain drain. Lincoln talks about how government price controls have driven out solar mini grids, to the detriment of everyone involved. Why do governments make policies that ultimately hurt their populations and drive away investment? Does that happen even here in the United States?
