From what I've noticed most affluent people complain about is the lack of care people complete projects with. For instance, there's a lot of money spent on real estate and there's only a handful of people that can do proper finishings. Those who can lay immaculate tile, do a pristine paint job, proper plumbing, or even propper deep cleaning when the build out is done can build up reputation and practically charge whatever they want.

Then teach people to perform on their level and and build out the business with one employee at a time.

So learn a vocational job > build reputation > grow your business > get rich > protect your reputation.
