I did not mention Pena. I said Paraguay has "never emerged from being run by nazis", which is a completely different thing. The Colorado party still runs Paraguay.
And almost all of your other statements are opinions, just as mine are.
I have made things all my life. I have visited Argentine factories, I have dealt with Argentine wholesalers, I pay attention to country of origin for many things. I have done the same in the USA. I stand by my general position that the Argentine market has more local products than the US one. Certainly, not everything made in China is crap. I own a very nice chinese built self contained power hammer for forging metal, which weighs around 3500lbs, which I bought new, and like very much. But I prefer Argentine made Ombu or Pampero work clothes to chinese made clothing when I run it, forging red hot steel.
Nonetheless, you have not addressed, at all, why, exactly, Uruguay is so much more expensive than Argentina.
I believe there is a supportable argument that one of the major reasons is that Argentina has a manufacturing base, where cars, steel, machinery, electrical devices, garments, textiles, and much more is made, and, to some degree, exported.
I also believe that its pretty indisputable, that, regardless of whether or not the most recent president was racist or not, Peron, himself, in the 1940s, placed into law policies supporting Argentine industry.
You can like them or hate them, but the fact remains that he felt it important that Argentina made, domestically, jet planes, trucks, cars and buses, steel, machinery, and hundreds of other products, and he instituted a system or tariffs, duties, quotas, subsidies, price supports, nationalized industries, and government programs that made that happen.
Uruguay did not do that.
I think it helps explain the difference between the two countries.
