> there should be a team of professional adults

Look up how much housing costs, and how much professional nannies cost, in a location where the software engineer and lawyer are making $500k combined. And you'll need at least two nannies, one overnight, one during the day. I don't think the math is going to work out very well. Also, there are a lot of greedy jobs that don't pay nearly as well as $250k, especially early in career.
