This is the "big lie" used to justify keeping it low. The reality is that minimum wage hikes hit profit margins first and hardest, inflation next and jobs get hit last (maybe if it gets hiked $10 / hour).

Minimum waged labor is very, very, very inelastic. For better or worse the people who clean your toilets and serve you coffee in the mornings are extremely necessary and very hard to substitute. Much more so than most middle class jobs, even.
Business lobbies know this to be the truth, but they know that they will get nothing but by asking the general public to have sympathy for their falling profit margins.
So, they try to scare the shit out of you by claiming that they will be forced to fire you instead (e.g. this expensive billboard for the national restaurant association demonstrating their concern):
