‘Henry Ford invented the 40 hour work week’ is a very strange way to say ‘Henry Ford claimed credit for changes he was forced to adopt after a hard fought campaign by the union members he despised’.
Love the ahistorical mythologising of the ‘good capitalist’ like Ford doubling their salary and ‘giving’ workers weekends occurred to him in an inspired dream rather than being the actual demands of the labour movement.
Or that Ford was the first to do these things when they were achieved by movements around the world *centuries* before.
