The nomenclature for leftist is slippery. They claim ‘liberal’ until it becomes toxic, and then they switch to ‘progressive’ like when Hiliary claimed to be a Wilsonian progressive and Margaret Sanger progressive. Both were deeply flawed, intensely racist individuals. The basis for this liberal progressivism is Marxian, and Orwellian, in that it is not progressive at all, but is in fact regressive to individual liberty.
While classic liberalism is based on individual liberty, the Marxian model is based on conformity in order to support the collective. Individualism is seen as non-conformity and subject to discipline.
As far as unions go, they have their ups and downs. They were important in establishing fair labor standards but they went overboard. A union welder told me he got in trouble for turning his machine on to start work one morning. He was told that they had a machine operator who would do that and he was taking another man’s job away by turning it on himself. Another union man said that it was his goal to see to it that the company didn’t make any profit.
Some union apprenticeship programs are excellent. Apprentices come out, money ahead, highly skilled, capable of doing excellent work. When locals have the right attitude and can send these tradesmen out, they are the preferred competitors, as the quality of their work proves to be economical over time.
With labor laws as they are, there’s no place, or need, for public sector unions. Teacher, police and fire, air traffic control, etc. Civil service jobs included.
