In UK, I started work just before Margaret Thatcher came to power, and her governments certainly reduced union powers, and of course put back substantial Nationalised Industries back into the private sector. (When the process started Gas, Electricity, Coal, Water, Telecoms, Railways, and Post Office were all state controlled, all now in private sector. I actually worked for a massive state controlled company at the time, and naively welcomed the change on the grounds it would make it more efficient. Do not think it did!)
The successive Blair governments did not really roll back any of the fundamental Thatcher changes.
Governments since? I am much less interested in politics than I was, but I do not think they have really changed things massively either way. (Possible exceptions being Brexit and possibility of Scotland exiting the Union, of course. But personally, I do not think either of those will affect how equitable or not British society will be in long term. I voted to stay in EU, but do feel any less free as a result of leaving.)
So I guess..in a long winded way…I’m saying I think my own country has regressed a bit in same time period in which you think yours regressed. But maybe not as far back as to the “Robber Barons of the Gilded Age”.
