At 15 dollars and hour, there would be no legal employment in the US for a huge chunk of the population. Australia has chosen to keep those people on the dole, but this doesn't fly in the US politically.
Obviously a generous and comfortable dole is the other side of the coin to a high minimum wage in a 'capitalist' economy, and is even more economically beneficial.
And further entrenching the underclass, incapable of ever getting off the dole. Your lordship, really, hates the poor, unless the satisfy his sexual needs.
Not like anybody escapes the true underclass in the States anyhow.
