To help you conceptualize how that is possible: 100 years ago the world population was 2 billion, and now it is 8 billion. While the housing stock is also increasing with that population growth, the actual amount of desirable land does not grow as fast. That's why -- for example-- the US gov't in the 1850s could just hand out 40 acre plots of land to people. They can still do that, but it has to be way out in Alaska or something.

A hundred years ago it took much more labor to produce enough food to feed a person. Before the industrial revolution let's say 90% of all people were farmers. In 1850 in the US that was maybe 50% of all people were farmers. So the % of GDP going to food was much higher. Now 1-2 people can feed 100 in the west. That means less of your income proportionately goes to food.

Similar declines in the amount of labor required to produce a thing are happening in manufactured goods. So it may have once taken hundreds of hours of human labor to build a car, but now it takes much fewer.

So the wealth of everyone is going up faster than the supply of desirable land. That does mean people are getting priced out. But also people find ways to live on less land. Before the industrial revolution most families needed a farm to survive. Now many, many families can live in an apartment building in a city that takes way less land.
