I think the dispute is more wether 75% rent is a likely choice in the million dollar scenario.

(vs the contentment with remainder)

This entire thread is so strange to me, if you're spending $750000 per year renting, shouldn't you be buying $750,000 properties once a year instead?

I think the idea that the grandparent commenter was pointing out is that pointing to higher percentages of income going towards rent is an overly simplistic metric. If the percentage of income spent on rent goes from, say, 20 to 40%, but average incomes double then the total amount of post-rent income still went up by 50%.

We're talking about San Francisco. There aren't any $750k properties. ;)
