You have gotten $75k/year though. Take two people X and Y, both have $500k in the bank. X buys a house with it, Y sticks to renting. A few years later, they want to move to another place with the same costs. X's house now sells for $1M and he is able to buy a new place for the same money, thus his new house effectively only cost him the $500k he had spent years ago. Y, having not bought a house previously, now has to pay $1M, which he does not have.
