My dad worked as a programmer (idk the official title) for a decent sized company. Always contributed to his 401k enough to get the employer match, and added more each time he got a raise. Between the paid off mortgage and 401k balance his net worth is over $1 million. He was only ever an employee, I don't think he exploited anyone. Bought himself a new set of golf clubs to enjoy when he retires. His last set was one his family got him for graduating high school.
