Over the past few decades we have seen many problems caused by greed. Many of the rich have used the "greed is good" as an argument and business practice. However there are many problems with that philosopy.
The first is that "greed is good" is only circumstantial. Greed is only seen as bad if there is a negative outcome, but other than that it is seen as good. The chemical spill in West Virginia for example, the company last inspected their facility in 1991, but until the spill acutally happened that was seen as good greed.
Second, people assume all the money we give to the rich through tax breaks will be funneled back into the economy. Some may invest in the stockmarket or spend it on luxurys that don't produce many jobs, while most hold onto it for the rest of their lives or give it to relatives. The idea we have is that that money is seen like a donation, with all of it being used, and not pocketed on the side.
No one wants to pay for unnecessary jobs, but the ideology of doing more with less only causes problems. The workers are forced to take on more than they can handle and the jobs aren't done the way they should be. The quality of work is sacrificed for money.
Lasty, trickle down economics cannot work in a greed is good culture. The flow of money is slowed, by the time it reaches the poor they barely have enough for themselves. To prove my point, about ninety percent ot the money has stayed on wallstreet. I apologize for not being able to cite a source.
The solutions aren't very clear. First, people need to admit to the cultural problems of the younger generation. Sorry, but we can't expect the rich to change if we aren't willing to. Second, we have to ask anthropologists why cultures change and how we can change it. This isn't something that is going to change overnight, but something that has to change if society is going to work properly.
