It is not necessary, nor appropriate, to sow dissent and misrepresent employees or constantly to threaten industrial action.
The trade unions and the Labour Party... failed miserably. Instead of giving concrete support, and calling upon workers to take industrial action, they did nothing.
Action is the foundational key to all success.
If you go back to 1800, everybody was poor. I mean everybody. The Industrial Revolution kicked in, and a lot of countries benefited, but by no means everyone.
