The question is simple: if the business does not make enough money, it will not be able to pay any money. By establishing minimum wages the only consequence is that the less-qualified and low productivity workers will be thrown out of the job market.
Because employers don’t pay a wage that is higher than the value of an additional hour’s work. Them, as well as workers, are there TO MAKE MONEY, not charity… Ignoring this fact usually brings catastrophic consequences.
Remember: it is always better to make 5 dollars per hour than 0.
