Upgrade infrastructure, yes.
But the rest

What kind of message does that send?
That people shouldn't be held in servitude to capital?
Don't take out debt you can't repay.
Don't give people access to debt they can't repay.
Funny the banks got billions of free money from the tax payers but the tax payers can't ask for it back in debt forgiveness.
The entire system is like it is because people who make interest off of capital want it that way.
As long as the people in power have access to enormous wealth, and want to make money doing nothing while that wealth earns interest, then they will continue to manipulate the system to ensure that as many people take out loans for as much money as possible and as long as possible. They MUST feed the interest-based system.
That's why you get deductions for mortgage interest - so that the interest-monster can be fed.
That's why capital gains taxes are less than high-end income taxes - so that the interest-monster can be fed.
That's why the Fed sets interest rates where it does and does everything it can to keep down inflation - so that the interest-monster can be fed.
That's why everything is designed to encourage you to take out that mortgage, get that car loan, take out those school loans, get that business loan, etc....
What message does it send if we forgive a ton of debt? Maybe we throw a wrench in that system. Just a small one.
But honestly, we need to do a hell of a lot more.
