Young people have most or all of their net worth in cash because they aren't worth much yet, and you need cash to pay for things. They are also more dependent on their job, which pays them in dollars, because they will run out of money quickly without one.

Given all that, it baffles me that young people don't identify the economy and inflation specifically as the most important political issue. They're always complaining about stuff that people tell them to care about, not things that materially affect their ability to sustain themselves.
