A recent immigrant who was brought here from a foreign country by a "relative" and then told to work in their shop for $1/hr or be sent back home (or worse) would gladly take that $1/hr job. This actually happens in places that don't have labor protections.
And not just immigrants. Anyone with an abusive parent or partner or any situation where one person holds power over another.
True, but in the US, you have to commit illegal acts to do it (like paying under the table), putting the employer at risk and lowering the chance that it happens.
If there were no minimum wage, you could put the person on payroll and be completely legal in your actions, allowing the employer to exploit unknowledgeable employees.
And not just immigrants. Anyone with an abusive parent or partner or any situation where one person holds power over another.
Hence "this is how you get slavery".
