I wouldn't be able to hang out with them as much (they'd go do a lot of higher-cost things that I couldn't afford anymore).

I'd have a shittier apartment (they'd drive up the price of the nicer ones, if we're talking about a significant sized group; if it's truly just immediate friends, then instead it's just "they'd all move further away to a nicer area").

So I'd have some more toys but would have a big loss in quality of my social life. Pass.

(If you promised me that those cracks wouldn't happen, sure, it would be great for them. But in practice, having seen this before, it's not really realistic to hold the social fabric together when economic inequality increases rapidly and dramatically.)

No you would have the same house or better. That’s part of the condition.
