Your logic still does not make sense.
How will product prices go up when employers/employees stop paying FICA ?
From my perspective as a small business owner, I’d be able to give better deals to customers if I’m paying 15.2% less on employee wages.
Excluding Employee paid taxes, there is only 7% embedded taxes in the cost of goods. Now add a 30% sales tax on the item, and poof, prices go up roughly 20%. As far as wages, your costs are reduced 7.625% since the other 7.625% comes from the gross pay of the employee. The employer will only see half of the savings.
