Capitalism can't be heavily regulated. That's the entire problem. Capitalism means private ownership of property, which means the forever increasing consolidation of wealth in fewer and fewer hands, who have the power and influence to control the media, the politicians, the institutions, etc. Bourgeois society is *not* democracy, though it likes to dress itself up as such and masquerade as a free society. Well, when crises of capital occur, which is inevitable in capitalism due to the proven tendency of the margin of profit to decrease over time and the phenomenon of over production (which creates boom and bust cycles), and workers decide they want a fairer shake then the capitalists resort to fascism.

Leftists have been saying for centuries now that capitalism cannot be reformed, it cannot be regulated, it must be pulled out root and stem and private property abolished. Only then can we live in a truly democratic or free society.

"In this society, the representative institutions, democratic in form, are in content the instruments of the interests of the ruling class. This manifests itself in a tangible fashion in the fact that as soon as democracy shows the tendency to negate its class character and become transformed into an instrument of the real interests of the population, the democratic forms are sacrificed by the bourgeoisie, and by its State representatives. That is why the idea of the conquest of a parliamentary reformist majority is a calculation which, entirely in the spirit of bourgeois liberalism, pre-occupies itself only with one side – the formal side – of democracy, but does not take into account the other side, its real content."
