You could make this same video today easily, it's a propaganda piece designed to sell the city.
Erm, Peronism was literally banned in Argentina from 1955 to 1973. You're stretching quite a long way to blame it for the failed policies of almost 2 decades of right-wing governments from who seized power in a coup themselves in 1955. Somehow, despite having had no political power whatsoever for 15 years, the problems of the 70s are because of them.. Lol.
You even manage to pin the last military dictatorship on it.. Quite grotesque.
