Is the free trade hurting blue collar workers?

Of course we live in a global economy. But we did in 1970 too. It is not about isolationism but Russia proved several times over that with countries and populations our size that is actually possible. That being said the tariff thing is just doing what every other successful economy is doing and it is why they are successful and why Canada and the US used to be successful past tense. Also credit is not wealth my friend. Just because you can go into debt to buy something does not make you wealthy. You seem to be missing that these free trade agreements are a key component in creating the very inequality you speak off. It has gotten so bad that US and other first world companies are not only contracting jobs like call center work to India but those Indian companies are sub contracting the work back to "right to work for less states" because it has gotten to the point that the Indian middle class will no longer work for the poverty wages that desperate Americans will. The reason your wages are going down is because these agreements force us to "compete" with 3rd world workforces to the detriment of everyone except the capitalist. So this is not at all rearranging deck chairs on the Titanic. The wealth inequality is no accident and it is not coming out of nowhere.
