People who make enough money to save 20% of their deposits probably aren’t going to bother with some convoluted system to earn a maximum of $3000 interest annually. You could make more with AMEX points.

You make amex points if you spend money. I barely spend anything I make (and whatever I spend mostly can't be on cards) so for people like me this will be ideal. Given the pandemic and wfh boom I doubt I'm alone. I'm also extremely averse to every speculative investment bin right now, so if someone guarantees coverage for 3% inflation I'll happily give them my money.

Here's a big one:
