Cost of living and profit

Archergirl

I don't know where this belongs, it's a question............I left school at 15 so not as clever as you lot so I have a question.....

There is a cost of living crisis because everything is going up so the government is going to raise the interest rate to try to control it.
But it's going up because the makers of stuff (or the owners or whatever) are charging more for it.

I heard on the news that supermarkets profits have gone up from millions to billions, as have the energy companies and fuel companies.
The prices for all of these things has gone through the roof (thus I guess causing inflation)

Now surely if the government put a cap on profit to millions instead of billions (they were ticking along nicely making millions before the cost of living crisis) prices could come back down, and inflation would be gone....
I know I am simplistic but please tell me why this can't be done.( I bet all the shareholders come and tell me this.).............
