I'm currently looking for work and out of the hundreds of places I've been to/applied to, none pay less than 15. Wawa, Walmart, McDonald's, every major employer. Maybe you can find the one small business trying to pay less, but it's not an indicator of the market as a whole.

And minimum wage does nothing to stop wealth inequality. Until companies do not have an incentive to pass along prices to consumers or exploit the labor market, the only thing minimum wage does is increase inflation.
