What are the downsides that prevent more people from working in high-income countries, and then retiring in low-income (and cost of living) ones?
I should think the primary reason is due why those countries have a higher standard of salary - its not what you get, but what it buys you. In a high-salary, low-exchange-rate country like Sweden, you get a lot of services that your taxes buy you. Healthcare and quality of life in a stable country is something you want when you get old (note that your viewpoint might be very different when you're a kid). Moving to a country that has less impact on your finances is often because that country has significantly fewer services to offer. So a Swedish citizen might think about moving to a 3rd world country and find that their retirement income isn't sufficient to pay for the kind of lifestyle they actually want, such countries tend to be pleasant to live in only if you are exceptionally wealthy.  Now this kind of thing does happen, but only "within reason", there are a number of old people who retire to the coast (in the UK at least) and many people who used to work in London who retire to the south west. For them, the idea of moving doesn't seem so bad as they are moving to areas where many other people in their situation have also moved. See Florida for an example for US citizens too.
