If a single billionaire bought all the heat pumps it would result in heat pumps becoming incredibly expensive overnight. The billionaire would be overpaying for every single one and it would take years for prices to correct

This is literally what taxation and subsidies are for.

Sorry but haven’t even read the article when it is using such a stupid headline, or did you decide on that, OP?

What if we just redistributed the wealth so that we had no more billionaires?
