People need to stop moving out of their parent's house if they can't be stable. That's the root cause of a lot of the problems in the US.
This is now happening.
This assumes, among other things, that they come from a stable home that has space for them and access to the things they need to create and maintain an income stream.
We need to change money flows and redistribute wealth so people can have a hope of saving some money, because they actually can make more money than they absolutely need.
And then you have the same people complaining about low birth rates...
