“The rich” didn’t all get that way from an infinite lineage of old money. Some hustled their way from the bottom believing in the American dream of an honest return for an honest effort, skill, and/or talent. It is not fair to lump them all together. Also, not too many people have been hired by the poor, after all.
Hustle sounds about right for a high percentage.
I got my first job from a homeless man washing rats in the Bowery. Paid a wooden nickle and hour, and I was happy to have it.
