> Is your point that student loan debt is flowing to the administrators of higher education and making its way back to the economy to push up home prices?I'm saying taking on debt comes with the assumption that you can create new value, over and above the debt value, in the future. Normally, lenders require a promise of value you have already created (security) to fall back on if you fail to create that future value in order to keep things in check. Not so for student loans, though. They are assumable by those who haven't created any value in the past, and who may struggle to create new value in the future. This creates a distortion in the economy.
> why did it only start to occur in the last decade or so
Why do you say that? As far as I can see it started in and around the 1950s and really started accelerating in the 1970s. Before that housing prices were almost perfectly stagnant.
> why does this specifically impact housing prices and not other CPI items
Mostly a function of what else are you going to buy? I wouldn't say housing is the only place that has attracted money (remember Bitcoin?), but may be the most notable.
If everyone saw a share of the money then you might find competition in buying things like bread, but if it is only the top 10% (for the sake of illustration) taking the proceeds, there isn't much pressure for them to pay more for bread. Only for the things the other people in the "top 10%" want to compete for.
