If inflation causes your costs to go up, can you, and all the other plumbers in your area just go ahead and raise your prices to make up for it? Yes… People who are paid by tax money can’t just raise their rates. Even if they go private, Medicaid (in US) tells them what they can charge.
Anyway, I didn’t mean to disparage plumbers. I was using them as an example of an equally important part of society, but that gets to adjust their prices as needed instead of having to wait for a literal act of Congress to adjust prices and pay for inflation.
C’mon man… My list includes 5 jobs that literally save lives… Your figurative life saving can get right outta town
