It's not a yes/no proposition. it depends 100% on how far and how fast. To just say $30 - which is more than 4x the Federal rate, and not know what inflation does or doesn't do over the time period of the increase or what adjoining jurisdictions or the State of NY (otherwise known as your business competition) do, you are talking about the possibility of dislocation. The when you are talking $7.25 to say $12.00 and do it at the federal level where the guy across the street is not exempt, you are in a whole different world in terms of effects - or lack of them. The level of impact of an increase does go to zero when you are starting at low rates and making relatively small increases. In general US MW has always been so low and the increases so small that people who argue they are the end of world are always wrong - no argument there, but that doesn't mean there isn't a place where the level and difference won't have an effect. Economics is always about degrees.
That's why it will be a measure of Mandani's actual political/economic acumen. It's not where you start, it's where you finish (assuming he eventually wins).
