I wouldn't blame trade deals like Nafta and then broad brush all trade deals as bad.
Trade deals are generally good for economies of most nations. It forces a country to develop its own comparative advantages. In the case of Nafta, which was developed by Old Man Bush and signed by Bill in an era of pre-Internet days. It maybe obsolete in parts but the fact is that it allows fairer competition amongst nations within a trading bloc.
Then like most competitions like the EPL, where you have oligarchs or Oil barons funded organisations, clubs like United need to find another way to survive and prosper -- thus those silly marketing agreements. You find a way within the framework like the EPL.
Like the EPL, as in Nafta, each club/nation needs to find its strength and leverage to survive otherwise we get relegated. Trying to protect manufacturing, coal mining jobs is akin to asking the league to play according to pre-EPL rules when the TV money from Sky became a huge factor for everyone.
The criticism of governments would be to re-train the workers but that takes two hands to clap ie workers wanting to change and also having relevant re-training programmes to make these former workers employable. Many of these re-training schemes have been cut or have no landing strips for jobs later.
Going forward, the TPP is in my opinion in more of a long term political play rather than a trade deal. I also ensure that the US is a relevant player in the fastest growing region in the world. It also provides the various countries, a more equal trading partner in the US and a counter-balance to China's dominance in the A-P area.
So trade deals arent just about jobs.
