Sanbuenaventuraman, I agree the economy here is very bad when many Ticos can hardly afford to eat, let alone buy a beer at a bar or restaurant. Some I know simply don't go out to eat. But then I don't hardly either... but is that important to me? No.
RTV can cost hundreds of dollars to pass, tickets are high, appliances, electronics, and cars and gas high etc.
BUT I still say it evens out for gringos because the labor is cheap here (mechanics and doctors and dentists and laborers all much cheaper than USA), and property is much cheaper and building is cheaper - at least in the mountains or for comparable views etc in the states.
Sure, buy a luxury home on a prime beach property and it's going to be ridiculously expensive. Just like the states, more or less (though still less here).
[For sure it's expensive here if one builds a huge luxury home with a pool, buys an expensive gas guzzling car, drives all over the country regularly, has a huge a.c. bill, insists on eating imported food and at restaurants etc...
One has to be willing to adjust one's lifestyle to fit one's budget.]
If you want to live on a budget here you can. I do it myself and know many who do and all of those who I know, do say it's much cheaper here than the U.S. for a comparable lifestyle.
Example, I got by fairly well in the U.S. on $50k a year but lived in an apartment in a big city which I hated. Now I get by fairly well here on $18k a year. I eat out a little less, don't save much money, but get by and don't "want" for anything really. In fact am happier here because I have my own home as opposed to renting, and have a big piece of land to enjoy the nature.
But , yes, some things are expensive here, more than they "should be".
