Thing is, the concept of a Free Market is a concept of 'folding' profits back into the industry, whilst that is happening, there is no problem with it, but the problem was that it had got to the point that so much was being skimmed off the top that there was not enough left to fold back into the industry, profit became more important than maintaining quality of service, cheaper and cheaper methods were found for producing goods, but the savings were not being reflected back onto the customer.
Greed is one thing, if someone complains that an investor is earning a lot, then tough, should've got into the same line of work themselves, but when that greed has got to a stage where it is actually damaging the economy, rather than keeping it vibrant, then there is a problem to my mind.
