> Startups were you get equity. Large companies where you can progress to high salaries if you are able to rise. Starting your own business and being competent at it. Working on commissions in an area where the commissions can be large -- true sales, or real estate. Being a professional, e.g. doctor, accountant, lawyer, has traditionally had high wages and you often run your own business.
This is all great if you have an aptitude for participation in the knowledge economy. That's not everyone. There used to be much more high-wage blue-collar work available to those who didn't fit that mold, but that has been ebbing away over time as America's manufacturing economy has been hollowed out.
Stronger unions and collective bargaining in the dwindling blue collar work that still exists is my only idea for how to improve things, but I'm not an expert.
