you can get a job as a long haul truck driver in texas with no education and paid for training paying 80-100k and live in an area where houses cost 300k, within 5 years starting from zero with no education you can own a home and have a nest egg big enough to become an owner operator or invest in a small business.

so thats the floor for anyone willing to put in a few years of work.

It says non-backbreaking. Truck driving is one of the highest risk jobs towards one's back.
