If you are talking about people having a hard time setting up small businesses because of "big business" competition, then talk to the Progressives in both parties that think that gov'ts can pick winners and losers and get cozy with "big business".
I'm an Independent Constitutional Conservatarian. I believe in the free market - that means NO ONE gets a special hand out - no business, no individual. LIMITED GOVERNMENT. Whether you are big or small, you stand or fall on your own merit.
That is not what the Dems are about. Republicans are more so about that, but still infected with Progressivism.
