Those things happen
If you just have paper money with inflation and crony capitalism:
If you think why does it happen despite so much surveillance: http://www.zerohedge.com/contributed/2012-12-18/big-brother-spying-didn%E2%80%99t-stop-connecticut-school-shooter-%E2%80%A6-or-911
Then you just see something in the default state of not being able to work. Government can not work if everyone is a suspect and if nobody can count on not getting more poor by the day.
All this explosion of high incomes would not happen in a world without credit-money. People would have to "earn" their money. So they are just "getting it".
You do want less poverty. Then stop burning money for states, the military, the diverse agencies. Flat you tax to something at 10 % and let the people care for themselves.
