Actually you can get free health insurance for a family of two if living on 500 a week at least in some places. Full time at 12.50 or 25 hours at 20 an hour or anything in between. If that seems like a lot consider 2 people can easily eat $500 in food at present prices, rent can easily cost $1200 for a shitty apartment in a shitty neighborhood. yada yada. This is basically about nothing to live on.

Notably many families have one worker because one has health problems or is needed to do childcare because the amount they would earn is actually less than childcare alone let alone benefits + childcare expenses. Many folks who are disabled in fact receive basically no help of any kind if the other partner works or if they cannot spend years fighting it out in court.

Lots of people already living marginal lives will be effected.

Another example consider older relatives too young to receive medicare but not employable because of some combination of age and health. They might live with relatives but rely on government health insurance.

Another yet consider people who who living with relations providing childcare and relying on the government for health care. They effectively ARE working for board but making them try to compete with 20 year olds to work at McD will likely result in damage to the family and the person who will lose health care if they can’t work or the family who will lose childcare if they can.
