For the love of god woozy, brevity, learn it. For someone who claims to have a degree in economics your post is pretty disheartening.
You have some absolutely asinine statistics. Please state a source and the year they came from and I will give a reasonable explanation for the numbers. Trickle down theory has lost its gripping in the world ever since there was outsourcing, but that is another paradox in its entirety.
Your examples of monopolies simply take on an issue with relatively little barriers to entry. A bit different story now instead of when the economies of the world were very simplistic. Take a look at how many have been busted up that would severely fuck the consumer...want a list? Also your standard of living comparison doesn't explain the dominance of many other countries over the US in a lot of aspects of well-living. Health, education, etc. You know there were two world wars right? That tends to decline the standard of living really well.
If by help the poor out you mean investing in human capital and tangible investments rather than absurd amounts of derivatives on international markets then YES I guess I am crazy.
If you want to pull out simplistic examples I could tell you hundreds of inventions from philanthropists who merely wanted to better the life of everyone else. This wasn't a majority but merely a consideration.
Obviously a capitalistic economy has had great implications on our spurred growth. But the assertion of your tirade that it is everything and anything and a lassiez faire approach is to be had makes people like me who have studied the subject extensively look on with disgust. The breadmaker was an awesome analogy, but is not made for the real world.
