You mean, like, Cuba? I think such governments have its pro's and con's.
Pro's: Cuba has the highest education rate in the entire 21 Latin countries including Spain.
Cuba provides that education free of charge; even into university level.
Everyone gets to have a home and food if they work. (they kinda have to)
And that leads to this point: no unemployment.
Con's: being communists, everyone (including US) bans trade with Cuba. (otherwise it would be a very wealthy country)
There is a limited amount of freedom
Having trading banned, there is almost no food, or supplies.
[I'm sure there's others, but I listed the main points]
"if'ys" -(things that may be good or bad depending on the individual)-
Even though poor, you live an averagely peacefull life. You don't have to worry about getting mugged at night.
Theres not a whole lot of tourism. (which destroyes the island) -[trust me, I know]-
You get to follow a leader who brought your country into independence.
