Uruguay is small, slow, and sleepy. Its also expensive. There are a fair amount of expats there- they keep their lambos and range rovers in their million dollar summer houses. I once saw an original Shelby Cobra in Jose Ignacio, with Uruguayan plates.
Alexander Vik, for example, had a Urugayan mother, but, to quote Forbes, "as a Norwegian who was raised in Sweden and schooled in the Canary Islands, Vik attended Harvard, where he won the Ivy League golf championship--twice. He brought up his children in an eight-bedroom Greenwich, Conn. mansion that once belonged to a Rockefeller heir, but he claims residence in Monaco."
He has thousands of hectaires and 3 hotels and a fancy ranch in Uruguay.
He is their target market for expats.
I have met wealthy Argentines who go there to visit their money...
