The world is rigged

So Robinhood is giving me 4.25% return a year on uninvested cash? So if you have $1,000,000 that means you get $42,500 a year by doing nothing? If you have $10,000,000 you get $425,000 a year by doing nothing? The rich get richer and the poor stay poor.

So my goal is to make $1,000,000 from dogecoin and then leave it on Robinhood and live off of $42,500 a year. Any flaws with this plan?
