Economists have been saying this for decades. It's another one of those things, though, where they say "The corporation income tax is bad for the economy, but it's only a little bit bad, so it's not worth getting worked up over." Just like the minimum wage and labor unions.
That our economy remains as strong as it is despite these obstacles continually amazes me. I run - more correctly, I am - my own business and the level of additional paperwork and government meddling that would be inflicted on me if I were to expand to the next level are daunting. I'm not a lawyer or an accountant, but I would need to hire both of those before I could get to hiring anyone to actually provide services to my customers.
Imagine where we could be with a sane system wherein economic policy written was written by trained economists instead of demagogic lawyers and their lobbyist friends.
