Or completely the reverse - all mandatory benefits as a percentage of wages. We kind of, sort of do that in Germany (up to about 50k for health insurance, 90k for retirement, I think)
How would increased taxes and mandatory benefits reduce the cost of employees?
Increased employee costs make an employer less likely to take risks and produce pressure to hire less workers. Then a few workers gain at the expense of others not having a job at all. Why do you hate workers?
It would make benefits a more constant cost per 1k paid to employee, making the cost per hour of a 30 Hr/wk employee closer to that of a 40 Hr/wk employee.
Come to think of it, that's probably why I have so many colleagues on 20-32 Hr/wk contracts... Mostly, mothers of young children. But they're doing the same sort of technical work others on full time contracts are.
