Pt 4 was a conflation. You made the assumption that when I said socialist/social democratic/people who believed in workers' rights I meant Bennite socialists. But I cannot have since I was referring to events as far back as c.1800, as I pointed out when mentioning Robert Owen (model factory) and the Quakers on prison reform. They cannot be 'Bennite socialists' because Tony Benn had not been born or promulgated the ideas which I termed 'Bennite socialism'. Because I am a Bennite socialist does not mean I will commit the error of anachronistic (moral) judgement and call people socialists who cannot have been, though their ideas may have become what is now socialism.
Your DF may have explained trade union history to you, but I think you have not understood it. Trade unionism (not Bennite socialism - too early) has been the backbone of workers' reform from the 1830s. Others also worked for workers' reform (I name one, the Earl of Shaftsbury - Anthony Ashley Cooper). Read about the Matchgirls, the Tolpuddle Martyrs (farm labourers unionising), the formation of the TUC (first conference in 1868), the General Strike, the forming of the Union of Shopworkers. Reform and workers' rights came from workers, their organisations and the many enlightened individuals who saw all people as worthy of a decent life. Opposition came from factory owners, mine owners, retailers etc. who saw workers' rights as an attack on their profits both by raising wages and by improving conditions.
This what I wrote:
You are entirely entitled to think Bennite socialists are a PITA. Most of the employment rights you have, however, were brought about by people who believed ordinary people have rights, i.e. socialists/social democrats.
You have conflated 'Bennite socialists' with 'brought about by people...' They are not the same people, though I think I ought to have said 'e.g.' rather than 'i.e.' - grammar is important. Nevertheless, that does not mean that 'socialists/social democrats' = 'Bennite socialists'. That's a leap too far.
