I saw this article last week as well. I'm a young 26 hetero male that's educated and
came here to Buenos Aires one month ago.
Life was very difficult in the United States. People my age have it rough. There is no work that pays more than $9, gas is almost 5 dollars a gallon, and with the price of rent 2-3 times more than BsAs, there is little chance to save money or pay back student loans.
Here is an article from last month detailing the problem for young people in US - older generation is 47 times wealthier than younger generation (the highest recorded gap in history):

(Oh... and what's even more interesting... our US government spends $5 for every person that's 65 for every $1 it spends on a person who's 20... what a great way to invest for the future)
All youths in US (and possibly Spain and Italy as well, though I'm not qualified to speak for those places) can do is stay at their parents for years after college to save money and try to take some shit pay job to pay off their expensive $150 or $200K degrees.
I am a self-employed web designer and search engine optimization expert and never had any need to work a shit job, BUT i have found living in BsAs to be much easier.
Rent in Barrio Norte = $350
Rent in San Diego = $790
Transportation Cost in BsAs = $30 / month (buses, subtes, FREE bicycles w/ bikeshare program)
Transportation Cost in San Diego = $120 - 200 a month ($30-50 a week for gas)
Food costs are more or less the same... some things like coffee are more expensive in BsAs, but other things like wine are much cheaper. Since California has numerous cheap burritoes for $2-3 that one can consume every day, it gets a slight edge over Bs As in cost of food.
