There is no fault - it is natural selection. Bottom line - not everyone can be a millionaire without taking all the money from the millionaires - but then there probably won't be any millionaires any more.
What do you suppose would happen if the 7.50 / hr folks started getting 50 /hr? The 50 / hr guys would start getting 400 / hr. your $3 burger goes to $10. Inflation. In a capitalisitic society you will always have income stratification. That is the built in incentive. Without that things get pretty dismal. A lot of life is unfair - just the way it is. I know what is like to be poor. In 1977 I was about a month away from being homeless. I was lucky and found work and pulled myself up through poverty to comfortable to slightly more than comfortable. No one helped me. I just lived within my means.
If you believe something to be true, it will be - in it's consequences.
