It's legal discrimination against people that are perceived as being low skilled labor. There's no substance to it as a fundamental policy. It's a bandaid on a hemorrhage.

It looks good on paper. Doesn't perform well in practice.
We need to be reducing barriers for minimum wage earners and employers. Not just telling them to deal with it.
The legal discrimination is the only real claim here. The rest is effectively meaningless, making bold but extremely vague claims that can't really be meaningfully evaluated and responded to.
And as for that discrimination, that's an... Unexpected claim. I suppose you could consider it a sort of positive discrimination in the sense that you're selectively putting upward pressure on their wages in particular.
Given it applies to ALL workers, however, it doesn't seem accurate. Especially considering how much some groups want to raise minimum wage. Some want to increase it beyond what some SKILLED labor makes, which means some skilled labor would get a federally mandated raise, which really hurts claims of discrimination based on level of skilled labor.
I would consider it much more of a general labor right. ALL workers who labor for someone else's profits are, according to minimum wage laws, entitled to some minimum level of wages.
Frankly, if your business cannot afford to pay its workers enough to reasonably survive, you're running a failed business. Your profits are being subsidized by your workers' support network, whether that be other laborers or some sort of tax funded social service. Every worker on food stamps is a corporate subsidy from your taxes. Every worker who needs a roommate to afford rent has their roommate helping contribute to business profits. Every 20+ unable to move out and living with their parents still has those parents contributing to corporate profits. Everyone who helps prop up a full time worker so they can survive in spite of their wages is covering the cost of business for them because they're the ones ensuring those workers can survive and return to work again. Without them, workers end up hungry and/or on the streets until they can't afford to work or become too sick or simply starve.
A minimum wage acknowledges this reality and puts the onus back on the employer. The employer wants labor. The employer needs a healthy, capable worker. Workers have basic needs that must be met economically. Why should business reap all the benefits and outsource as many of the expenses as possible? Why are we as a society responsible for picking up their shortcomings and seeing to the needs of their workers for them? Why do their profits mean more than put basic necessities? Just because their name is on the paperwork while our blood, sweat, and tears are on the tools and the products?
