You’re ignoring that what you output from your work needs to be… Outputted? So the issue is that you make less than you deserve for the amount of work that you do… If you make 25$/h and it wealth got redistributed so you would make 100$/h it doesn’t mean you could work 10h instead of 40h, your employer would still need you to 40h (or close to it, maybe you would be motivated by the increase in salary and work faster but that’s speculations) to achieve the same result.
If unemployment was at 75% and wealth redistribution happened to quadruple salaries then we could say “Instead of having 25% of the population working 40h/week at 25$/h, we’ll have 100% of the population working 10h/week at 100$/h so in the end the people that are working already will be making the same annual salary” but that’s not the case.
