Let the Free Market work?

I think that some republicans are clearly out of line when they say that the free market is supposed to work in this situation. Pure capitalism doesnt work because then you would have the strong manipulate the weak. We would create in essence a third world country. We have a modified version of capitalism that has served us well but we obviously got a way from the fundamentals. Those who say that this is seriously a market correction are seriously misinformed. There has to be some regulation of the system so that there is not manipulation.
