> Is this feedback process the explanation for why those previously underperforming and frequently complained about government departments have now been fixed?

Perhaps the constant demonizing of public services by private interests, (who btw often rely on government contracts to function), and certain politicians bought by these interests could be a contributing factor in why not?

But let me hear about how private healthcare and broadband is killing it please.

It seems to be mostly cultural inertia. People accept that the government department is underperforming because they expect government departments to be underperforming. Which they expect because that has generally been true in their experience. Which is the case because nobody demands better.

It's a vicious circle, but not an inevitable one. There are plenty of examples of well-functioning government departments, and in some countries there is no significant difference between the performance of publicly run institutions and their private counterparts (although there is of course plenty of variance within both of those groups).

Yes.
