The problem is that moving manufacturing abroad guts unions, its hard to strike or have any meaningful counter to it for a union. If they are threatening to lay everyone off and move abroad what could a union do to stop it? Only really a mass general strike which is near impossible in the US due to trade based unions.
same problem remains, decline in what number?
is your main point that gutting unions enabled companies to move manufacturing jobs abroad?
More or less, yeah

Mass strikes are also illegal, so a half assed one would be counterproductive.
