Capitalism has deception at it's very root. It's not about the fact that individual people within a capitalist society are bad. The entire incentive structure is set up to reward deception.
I think that's part of the reason you get this kind of hostile comedic routine from Bill Hicks (warning, there are plenty of F-bombs).
There's a pretty good movie on Youtube about the obsession in the US with being fit and it's relation to steroids called "Bigger, Faster, Stronger". There is some discussion with people that do photos for the purpose of selling supplements. These producers talk about how virtually every page you'd ever see in a magazine is a lie. Here's a clip from that movie where they shoot the before and after photo in the same day. Prior to that there's a person that makes lots of money selling supplements by means of such advertising. He mixes some flour and sugar, caps it, and sells a bottle of supplements that cost about $1.40 for $60. This is all thanks to Republican efforts from a few years back to deregulate these markets. This occurred thanks to people like Milton Friedman, who argued that the FDA is the problem. How many people are dying because of drugs the FDA has blocked from appearing on the market? Get government out of the way and let's see how great things will be. Take a guess at who it is that likes that kind of logic. Profit seeking scammers.
Socialism could be prone to the same criticism. Socialists want profits too. But the difference is on socialism you want to maximize profit per worker. On capitalism you want to maximize profit. Full stop. So there's a disincentive to increasing output for the socialist. The more you make the more you work. This disincentive doesn't exist for the capitalist. If he doubles output and doubles his profit his workload hasn't changed. He's not designing and building the parts. He just takes the money after others do the work. So the capitalist has a greater incentive to lobby Congress to suppress the kinds of regulations that inhibit increased production, or take that next step towards deceptive advertising. They always want more because it's all up side (more money) and no down side (workload unchanged).
