Maybe you are aware of the problem because you are a "proper lefty"?

A dying breed these days, unfortunately.

It is certainly glossed over by "market fundamentalist" types who tend to think let the market do its work is magic pixie dust.

Are there many of those left anymore? Everytime i encounter it and probe it, its basically some thin layer of paint on basically neo-feudalism "whose bread i eat those song i sing" mercenary mentality. Probe for the "not-a-real-ism" shism and if they do not want to go back to small companies fighting, but prefer big behemoths stagnating- not a true free market spirit- also a indicator, if they integrate well into hierarchies.

Meh, markets are a useful tool for the allocation of resources, but like everything you need to keep an eye on what they're doing and who's benefiting. And like everything you need to keep an eye on the people entrusted with keeping an eye on things as well.
