My argument is that, by the very nature of capitalism, big business always devours small business and becomes so powerful that it will eventually control any government that tries to reign it in. Doubly so in the modern age. If you have to work within the confines of a capitalist system, you need massive amounts of regulations to keep them in check, and even then it's damn near impossible and very open to corruption. It's better than nothing, but not by a whole hell of a lot.
