> Minimum wage limits is one of the best tools we have to act as a safety net
Minimum wage isn't a safety net at all. Minimum wage is a mitigation of the problem of low bargaining power of unskilled labor; it basically raises but narrows the tightrope above the safety net.
> If you can't afford to pay someone the minimum prices you can't afford your business. A minimum wage creates a floor.
Yes, it creates a floor for the value of labor you must be able to provide before you can be sustainably employed. (It also, simultaneously, sets a floor for what businesses will offer for labor even in conditions of labor oversupply; set at the right level, this makes it a net win even given the safety net problems it can exacerbate, but it is not the same as and does not remove the need for a safety net.)
> Allowing low wages means pushing the burden to everyone else not that business.
Only for the employees in fields affected by labor oversupply that would be employed in any case, and which are employed at lower wages.
Conversely, it also means lifting some of the burden off everyone else for the people who would not be employed with a minimum wage but who are employed without one.
> raise your prices or move to a lower cost country.
Unless you take the workers with you, “move to a lower cost country” means more people unemployed that are fully reliant on social support in the country that squeezed you out. Which is why minimum wage isn't a safety net.
