Johny- are you suggesting that I, or anybody else, should, instead of finding smart, interesting friends, hang out with the lowlifes, criminals, and drug addicts, as it would somehow be more "authentic"?
Frankly, everything you say is exactly as true for the USA as well. And, in the USA, I only hang out with interesting, smart people too, although there are plenty of average americans outside my "bubble".
The majority of EVERYBODY has been convinced they need a new car, a bigger TV, and the latest $3000 purse. I am not very interested in those people, no matter where they live, and I have met them in Singapore and Tokyo, Paris and Milan, Los Angeles and NYC, as well as meeting them in BsAs as well.
I have lived in, and visited, a lot of places around the world, and I am confident that, in my experience, there is a real difference between the current cultural life in Argentina and in the USA, and I stand by my statements. You may not have spent much time in the suburban sprawl of modern day america, but I assure you that, once you look beyond the large, but extraordinarily shoddily built houses, and the shiny new cars, both of which are paid for with borrowed money at high interest rates, you will meet a lot of americans who are exactly like what you describe- earning crappy salaries that are barely enough to cover their basic needs. Beyond that, of course, most are only one mortgage payment away from bankruptcy, and one minor hospital treatment away from losing their homes, cars and other shiny stuff.
If you prefer cheap electronics, and the ability to borrow a lot of money to buy a $500,000 house and a $40,000 car, come on up to the USA, plenty of other argentines I know have. Its a tradeoff we all have to decide if we want to make or not.
