Curious why do people lend stables to aave/compound at such low interest rates

Hi, I have heard US has raised interest rates and it seems banks are offering higher interest now. 0.75-1%. But when I see interest rates in aave/compound they are quite low (<0.4%).

I expected given these defi lending protocols are efficient than banks, I expected these interest rates to be atleast as much as banks in US. So, curious why people still putting in defi at such low rates.
