Some arbitrary number might be larger, but what makes you think you are actually making more than them?

Knowing our salaries adjusted for inflation and/or cost of living, the numbers aren't that close.

For example, in your grandparents’ time, food was around 50% of the average family’s budget. 30% in your parent’s time. Today, 10%.

In my grandparent's time a family budget consisted of 40 hours of salaried labour a week, today it consists of 80.

We’ve failed to scale the production of houses, however. It takes essentially as much labour to build one today as 200 years ago. This has left the actual cost of housing to remain fairly stable.

Again though, that's not very much. It costs like $150k to build a small brand new house, let alone buy a run down used townhouse, yet in places like Toronto or Vancouver that will run you upwards of a million dollars. That disparity between the real building cost of housing and the market value is why I can't afford a house when my parents could and why I've spend far more of my income thus far on over inflated rent then they had to.

That is a result of the fact that we are in a reactionary feedback loop where we let demand drive infrastructure investment instead of building infrastructure where we want it to go. We do not need to densify Toronto and Vancouver to be unrecognizable on the scale of Paris or Barcelona or Manhattan if we densify ours suburbs and turn our huge swaths of land taken up by existing small towns and cities into Torontos and Vancouvers.

We put a greenbelt around Toronto to stop urban sprawl (great!) but we did nothing to connect Toronto to other cities outside the greenbelt or to connect them to each other, leaving runaway demand for the only livable walkable city for hundreds of km, that also has nowhere to build.
