A total of 144000 people across the country are paid the Federal minimum wage.
1.4% of the workforce is paid at, or below that rate. These people are mostly waitstaff and tipped workers who make more than minimum wage.
There are other exceptions to the rule, but in the grand scheme they represent a minimal impact on the economy.
It, if you raise the minimum wage it will cause a shift in all wages. If you think inflation was bad before…start messing with that stuff.
