I'll accept that inflation is a fact of modern economies, but rent and the cost of housing has gone up faster than inflation, and income has not kept pace with inflation: the US minimum wage has been stuck at $7.25 since 2009, while inflation never stopped. And minimum wage itself as it is today is broken; on the one side, it seems to be more of a suggestion anyway, given that the service industry does not need to conform to it (because the assumption is that wage is stipended by tips).
And the other thing to consider is that if an employer pays you minimum wage, they would pay you less if they were legally allowed to.
