Here at Spain (and generally Southern Europe) we've been told over and over again that we have to stay competitive, which is just an euphemism for working more and earning less (i.e. becoming Europe's China).
In a globalized market with a (still) steadily growing population, competition is growing and therefore salaries are shrinking.
It's happening in all industries (e.g. tech firms offshoring) but also at homes. I don't know about the USA but here in Spain housewives love hunting for sales, buying as cheap as they can, and proud about it. Why are they surprised later when their children can't find a decent salary? Buying Perú's asparagus cheaper than in our home country (including transportation across the Atlantic!) is only driving prices lower and lower, which hinders the whole economy in the long term.
And now the USA is going to sign a trade agreement with Europe which will further increase competition and will drive wages even lower than they're now for both parties.
On the other hand, isn't this just leveling the playing field for developing countries? After all, for them to grow, we have to shrink.
