To actually believe something as stupid as you're claiming, you'd have to assume that the giant corporations suddenly decided to crank the greed knob in lockstep with a massive amount of money being printed in the last two years.
On top of that, you'd also have to assume that housing (which is in no significant way controlled by corporations) coincidentally skyrocketed at an unprecedented rate at the exact same time (along with equities) caused by a completely separate mechanism.
