That is not an amusement park, that is simply a street-faire. We have lots of them also in Mexico, and while they may look extremely boring, they are quite exciting at times (imagine a thing going round and round without a security belt... that is fun!)
I think it's pretty good considering they cannot get too many goods from the outside world thanks the the US trade embargo. Most of what they have they make. A lot of there automobiles are old 50s-60s cars that they have to make parts for themselves to keep running... Imagine that, people living outside of the comforts of modern living, and doing it by hand.
