It will cost an increase of about 20-40 more in taxes all around. FREE is never free.
The cost will be lost jobs, or layoffs, as employers do not want to pay the required costs of having a full time employee. This will also cost hundreds of jobs NOT created, because the company refuses to pay.
It will also cost many full time jobs.
This in turn will cost more people to seek welfare, which will drain that system.
It will cost many people to lose their way of life.
It will cost many to lose their homes, as their hours were cut, their taxes are higher, and their paychecks are smaller. They can no longer afford to feed or clothe their family.
All this adds up to losing the "American Dream"...
