Here’s an old Soviet Union joke. Sadly, it looks like a modern version would be appropriate for today’s UK.
Foreign reporter: What is your opinion on farm collectivization?
Soviet citizen: I agree with the policy of the party.
Foreign reporter: What is your opinion on the steel production goals?
Soviet citizen: I agree with the policy of the party.
Foreign reporter: What is your opinion on the increase in food prices?
Soviet citizen: I agree with the policy of the party.
Foreign reporter: Don’t you have any opinions of your own?
Soviet citizen: Yes. But I don’t agree with them.
I like Reagan’s better. I don’t remember it word for word, so I’ll use your version’s set-up:
Foreign reporter: What is your opinion on farm collectivization?
Soviet citizen: I can’t complain.
Foreign reporter: What is your opinion on the steel production goals?
Soviet citizen: I can’t complain.
Foreign reporter: What is your opinion on food shortages?
Soviet citizen: I can’t complain.
Foreign reporter: Don’t you have ANY issues with your government?
Soviet citizen: I can’t complain.
