Yes, but you're missing some context. Specifically the theory that, historically, business profits have always been limited to a set percentage of overall GDP.

Yes, but you're missing some context. Specifically the theory that, historically, business profits have always been limited to a set percentage of overall GDP. Everytime it tries to expand beyond a certain point, the market seems to correct either through increased competition driving that number down or labor pushing back to get workers a greater share, or government taxation/regulation (in a few rare cases) pushing this back down. It may seem like a historically high range of a few percentage points is no big deal, but it would be very surprising for that amount to stay constant over time and (when you account for compounding effects), it actually would be a big deal if it did stay at that level.
