Seems like this steadily increases the chances of a recession.
If consumer spending is distributed among a large group, you need a large amount of job losses/people deciding to tighten their belts to tank spending by a large amount. But if it's concentrated among a few? A smaller economic disruption could trigger a spending decrease of the same magnitude -- especially because a lot of that spending is now on shit that upper 10% doesn't really need and can easily cut back.
