the levels of wealth is hard to surpass as ordinary people, unless some major life changing things happen to you.
from 1mil to 5 mil is one level, from 5mil to 10mil is another, from 10mil to 30mil, or 100mil, or 1 billion...
I think bypass 1mil is very easy, bypass 5mil is very hard, if one can accumulate 10mil over lifetime, is great success..
