Not at all. The real estate share of income is probably at its highest among a lot of people who belong to the non-labouring class, but are far from ultra wealthy. But it's nice to have a scapegoat, isn't it?
If you belong to the 'non-laboring class' you are by definition the ultra wealthy. It's wild how much people are willing to slide goalposts to make themselves feel better.
While about 50% to 60% of the adult U.S. population are active W-2 wage earners at any given time, the percentage that relies on labor exclusively (meaning they have zero capital income or assets to fall back on) sits right around 40% to 50% of working households.
