The wherewithal has always been a problem. A lot of people don't think about the future so don't save. That often has little to do with earnings since I have seen people making 6 figures that are deeply in debt with no savings. About 50% of people that could contribute to a 401K are actually doing that. Biden has the right idea, 401K's should be opt out not opt in.
You can start an IRA with $100 or less. If you can't afford to save $100 in a year then you likely can't afford an IRA. FidelityGo is willing to invest the money in IRA accounts with only $10 so the problem isn't the amount of money needed to start one is too high.
Yes. IRAs need to be reexamined and restricted in the size they can actually grow to. An IRA with $100 million is ridiculous let alone one with $5 billion.

Restricting IRA size to 1000x the average US income would seem to be a reasonable amount. You don't lose it if it gets bigger than that. You just are required to move it to a taxable account.
