Content creators make plenty of Youtube, but it's spread out among millions of them which is why very few actually make any serious money. Also most content you wouldn't pay for, but will likely watch because it's free.

On the flip side, many creators have tried to go towards the subscription/patronage angle and far fewer are ever successful at that, with many making what amounts to a tiny trickle of supporting income while being burdened with much more responsibility to deliver. It's a hard bargain.
