It depends on what you define as "making someone else rich". I think it is a good trade off to have someone else shoulder all the business risk while I cap out at ~$330k at a reasonable senior level(Staff SE). IMO, $330k is "rich". Most people could retire from 5-10 years of working after reaching the senior level. Once someone reaches the senior level, I assume that the knowledge gained while hustling to achieve the senior level would let him/her dial down to the standard 40 hrs.
