I believe around 3% of our workers in the USA Make minimum wage, maybe 6% make minimum or close to it enough to be affected by minimum wage increases.
What I am saying is if it were 50% or more of our workforce at minimum wage, a hike could cause overall inflation, but with so few workers affected by it, it shouldn't be a cause of our overall inflation.
Even a McDonald's isn't paying all workers minimum wage....the franchise has a manager, a couple of assistant store manager, a book keeper for payroll, an accountant, and long term loyal employees that get paid more than their minimum wage workers.....
I think there are some sectors of industries that will be affected and prices may rise due to it, but it will not cause inflation overall in our economy, other things out there will....
