If it would destroy the economy if everyone did it, then it should not be doable in the first place.
This is like saying that if everyone had a small business it would destroy the economy. If you think a rental damages the economy, you have no idea what the economy is, or how it works.
Then it should be illegal to have no children, because if everyone had no children, we would literally go extinct.
What? Your comment doesn’t make sense. If everyone did any profession solely we would destroy the economy. If everyone became doctors, there would be no engineers or pilots. We would still be doomed. A diversity of vocations are necessary regardless of which vocation.
*Edit. I was thinking maybe you mean investments. But the same holds true there. AND because of hedgefunds and private equity it’s becoming more and more of all the money funneling into a handful of companies. All the economists are sounding alarm bells on this. But considering the direction our leaders are taking us, I think this is all part of the plan.
All so that none of their tenants can afford any of those four things without constantly struggling!
