It's cool how the fact that free market had been tried in nearly the whole world and is currently not working and destroying everything but it's ok, and how egalitarian policies as you say have been tries only 3 times with one really successful.
Yes, they failed for sure. I've witnessed the last years of that experiment, so I know . Cuba stayed alive for so long because of the support they've got from other socialist states. I can remember when my country often bought tens of thousands tons of sugar for astronomic prices for helping the cuban comrades, however we actually exported sugar too.
Well I've witness Cuba by my own eyes and sorry but I wouldn't have called that a failure.
Yeah cars are a bit old but it's not because of the economy simply because USA makes it impossible for any country to make exportation to it. And they had free education for everyone, free healthcare, both of excellent quality.
I don't call an educated population, having access to health care (one of the bests in the world, so good they launched international operations to help other countries) and to every basic needs a failure. Especially considering the embargo of USA.
