Huh? Either you have very little savings for someone on this site, or your "high-interest" account isn't high-interest. Ally Bank currently has 1.6% interest on their savings account, so you'd make $1000 in interest in 1 year with a balance of about $62k. If your savings account doesn't have at least 1.5% interest, then why do you have it? There's lots of places with rates of 1.5-2%.
Either it's some sort of 6-month emergency fund and CDs typically make more sense (ladder or not) or it's money you want to grow, in which case investing in index funds is the better approach.
You're not paying attention. The OP said it would take decades to make $1k or $2k; I pointed out it doesn't take that much money to make that in only 1 year. It's not that unusual to have $30k in savings, so that's roughly $1k in interest in 2 years, which is an order of magnitude lower than what the OP was claiming.

I clicked through a few of those offers. Each one has a balance limit (after which interest drops to near zero), monthly fees, sign-up fees, or requires you to generate banking fees through another service.
And how could they not? Finance isn't magic, and we are in a world of all-time low rates. There is no possible way these companies can be paying you 5% on cash without making it up elsewhere.
You'll never net more than $1000/year in one of these accounts given they have balance limits. Some folks sign up for multiple high interest checking accounts in order to park more money.
Anyway, 1.6% is going away given the Federal Reserve just cut rates by 50 bps yesterday. Expect an email from Ally soon.
