You are so incredibly dense. You said it yourself. The renter gets nothing. You get equity. The renter is who pays for your equity. You are lucky they don't burn the damn thing down on the way out.
I didn't say you'd get rich off of it. I am saying that the relationship is fundamentally and systemically imbalanced, in a way that still, even in the worst case scenario, favors the landlord. It is an unjustified and pointless hierarchy, that is fundamentally misanthropic.
And yes, writ large it favors the bankers over the landlords, but that is simply because the banks are landlords for money. Another unjustified hierarchy.
They are both fundamentally evil, it is just a matter of scale.
