This country lost something very valuable when Thatcher shackled the unions. Back in the 1970s, workers had a voice and it served as a bulwark against the more virulent forms of rapacious capitalism. When industrial unions were destroyed, that voice was gone and our democracy suffered enormously.
With the unions weakened, this country was comprehensively deindustrialized. Finance became the only industry that mattered. Today, trade unions only represent the public sector. Private sector workers have been disenfranchised and silenced by anti trade union legislation.
It wasn't just Thatcher who wrecked the unions. crypt0-communists infiltrated and politicized them. It gave Thatcher a cover for wrecking the only authentic institutions that could defend and articulate working class interests.
I would happy put up with a few extra days of industrial action to regain a degree of balance in our political discourse.
