Oh they used to make things better. They also got rid of the phosphates out of detergent which is why dishwashers don’t clean well anymore.
But we have many many more appliances now than we used to as well. LOTS of electronics that didn’t exist back then. IMAGINE if they used the same kinds of power needed in the 1980s?
What would suffer?
Power lines. Same old 1940s power lines CAN’T SUPPORT EXTRA LOAD.
Nobody wants to invest in better electric infrastructure so instead they make devices use less power so that we end up using the SAME POWER we did in the 1980s but for MORE stuff.
So that’s why they try to keep the loads down: Nobody wants to increase the electric infrastructure to handle more power per home.
