Tax, utility, mortgage and interest holiday?

The only solutions I’ve seen proposed to the current economic situation will just further help the rich (banks, rent-seekers, etc...). Give everyone $1000 and it’ll just be trickle-up economics. Poor spend to survive, rich grow their empires.

Those who are suffering right now are those who just got laid off. And there’s a ton of them, and almost all are living paycheck to paycheck.

What they need is a way to survive the next 1-3 months. To do this, they need to not pay rent or utilities, and not accrue interest.

So I propose the banks and credit cards don’t collect interest (on existing loans), that mortgage payments are deferred, and that landowners waive rent for the next 3 months.

Help me understand: what are the downsides of this for our society? Clearly the rich will be out a few months gain in rent but what else?
