When there is a finite amount of something and someone with more money wants it, it makes the price of it for everyone go up to make it so that some people can no longer afford to compete for the resource, making it available for the higher spender. (Yes there’s also infrastructure being built, but they will out compete us for that too)

Same thing with land & property on it, the working class can’t afford to buy housing now, because rich people want to use housing as an investment vehicle.

Food is another (though also tied to land ownership)

Ultimately it’s the same problem across the board and the solution is generally a wealth tax to prevent densely concentrated capital from distorting the market.

Specifically for these companies, they’re simply too big. They need to be broken up and need to be prevented from getting this size again. If they truly cannot be broken up, they should be nationalised.

Failure to address these issues will result in these companies and people holding a total monopoly on all the resources available. More expensive electricity is only the beginning.
