People who accumulate so much wealth that they are able to purchase a home in cash are very likely to be doing some kind of investing. Be that traditional investing, running a business, or finding careers in sectors which require lots of time & education.

So the invest/pay off home trade-off is there for everyone. Even for people like doctors, whose investments might not necessary be market-based.
