I lived in Uruguay 2 years, got robbed bad once. The country was decent in 2006 crime-wise but has gotten terrible. Recently my mother-in-law was walking down a street escorting an even older women to the hair salon in the middle of the day, got stopped by a guy on a moped, thrown to the ground and had her purse stolen. This all in a "good" neighborhood. Not with expats and money, just lower middle class, never many problems, everyone knows everyone sort of area. You can count on getting robbed, eventually. If not on the street then when you're away from the house. The latter is very popular and just about constant.
The city is now filthier than ever, major intersections are covered with 10-30 year old males with dirty water in a soda boddle and a filthy squeege, who will botgher you and ge tin your face until you let them "wash" your windshield or give them money, or cigarettes. They are filthy and rude and stink of wine.
There is an apartment building that has been under construction about 16 years. I think on or last visit they had finished the super structure!This is common in building construction, things take FOREVER. Building a house, you ahve to be careful, same thing applies, not to mention they skimp out on the quality goods, even if you ask for them, etc...
There is no choice. Gov't runs water, electric, internet, and all of them are horrible services that cut out constantly, are substandard and poorly managed. AND more expensive than Chile.
Food is more expensive than chile. Anything made int he USA is x2 in cost. A TV there costs x2-x3 the cost in the USA or chile. Cars cost x2-x2.5, literally, of sticker price in the states. Chile prices are more or less the same it seems. Gas is expensive. Insurance is decent.
Healthcare has gone down the tubes. the Socialist party in power made it so even private centers had to accept people that have the benefit through the state, via work, not sure exactly, btu now every decent medical provider is forced to take on WAY more patients than they can provide care for. Hospitals are dirty, doctors are paid next to nothing, and you get a number and have to wait hours for an appointment. It costs about the same for a mid-level plan there as a pretty good one in Chile, at least in our experience.
Those are the bad things

The good things are the beaches, the people (that dont rob you) the wood-coal asados, cheap to eat out compared to the US, etc.
By the way, Punta Del Este is its own world, not like most of Uruguay. But they have tons of robberies there, too. It has seriously become an epidemic. And now they've elected a murdering soliciast gureilla with no education president so, I doubt things are going to get better. I'm pretty sure they are going to get MUCH worse.
All of these are reasons we came to Chile and we were just speaking last night how it was probably the best decision we've made in our lives together.
