This is overly negative. It's not easy, but it's far from impossible.It is hard to accept...hard to get your head around the reality....you will NEVER find work here and probably you cannot support yourself in Argentina. All your skills are replicated here for what you would consider pennies on the dollar.
And a reliable, English-speaking, all-around handyman with good work standards and all his own tools might well be able to make some money here, at least enough to live on. It would all depend on how well said individual could market himself.
