Employer premiums are pre-tax. Individual premiums are not (unless you happen to be self-employed). Until that stupidity is fixed, "cash in lieu of benefits" ends up costing a lot more, because the employees have to pay taxes on that cash.
In Switzerland, you buy your health insurance yourself using post tax money (employers can't provide it); like ACA, they can't discriminate for pre existing conditions and it's mandatory to have insurance. Everyone is pretty much on the same footing.
