At the time the maximum wage was 4 times the minimum wage. If those at the top wanted a pay rise, then everyone else had to get one too.
Likewise my uncle used to work for a company in Switzerland which took the same approach, so whether it would work as national policy in a capitalist democracy, it certainly worked in his company.
It's certainly an interesting notion, and we can see from the above illustration how well off people at the bottom would be now, had their pay rises kept pace with those at the top.
