In my country young people don't have loans (edit, they may have some nowadays indeed) and we pay for cars out of pocket. Effectively The only loans are mortgages. Young people are not even able to build any debt now because they can't afford a house anymore. So they have a big incentive to see the interest go up again. But I guess this housing crisis is also driven by the insanely low supply, so building a lot more would also help.
