What is electricity prices went up with usage? So you get X kWh per month for one price, then after that it's 1.5x the rate. You could just do this on residential rates only so businesses aren't affected.
If those wealthy people are happy to pay a 5x or 10x rate, you can use it to install tons of renewables (with batteries). That's not something to complain about.
> Meanwhile, a middle/low-class family would be paying 1.5x the rate to keep the lights on home.
If it's not low, middle, or upper class, who do you imagine is paying the 1x rate?
