Telling people "if you're poor, you should just go somewhere else" is not a particularly compassionate response. It's literally the rhetoric of ghouls.
And why should cheaper countries—which are cheaper because of historical (and ongoing) exploitation—be required to solve the problems of richer nations (yet again)?
Beyond that, moving anywhere—let alone another country—is an impossible task for anyone with necessary family/social connections or particular healthcare needs, all situations more likely to be true among older people.
Rising house prices has in many ways been a trick to distract people from stagnating wages. It is a trick because the extra "value" of their house is only realised in exchange, which isn't actually possible much of the time, and in any case is usually only possible in a market where all other alternatives have also increased in price, negating much of the benefit.
For a brief period, it was possible for ordinary working class people to buy a home. This is a good thing. And while some of them will have contributed to the changes that leave us in the situation today, many of them did not and, in spite of having their own home, continue to face difficulties.
In your comment you appear to be conflating these people with richer folk, and you also don't appear to know how much elder care actually costs.
I'm not especially sympathetic to most of the anti-tax whining either, since it usually comes from the resentful rather than the struggling, but older homeowners are not a monolith.
A Taxi Driver is focused on criticising the authoritarian government of the South in the 1980s. It has the media blaming the uprising on the North, though the film has already shown that to be untrue.
Certainly there's going to be antipathy in some things. The Spy Gone North deals with that head on. But there are plenty of examples where it just doesn't come up at all. It's not like the prerequisite nudity in every single French film.
