constructing a twenty story two hundred unit building for 700 million vs four hundred forty story for two billion. exactly as it sounds. I don't know why you'd assume rich would disappear, I'm not saying it. I'm just saying building taller would require you to build more expensive and it's not the ratio that's holding it back. IT's good to hear you know how economics works for supply in a free market. Now apply it to the constraints of building taller. There's no way you'd get more more taller without dedicating more space to making your building work and make it less efficient.
