He gave his employees a raise after the election (and backlash). It demonstrates his insincerity about the expenses his business incurs, one of which is wages.
So he was claiming to live in a fantasy land, where the economy was crap and he wouldn't be able to afford employees, and eventually admitted to being in the real world, where the market is doing well... What's your point? And, again, what is this supposed to show or prove about minimum wage laws? Was that the "insincerity" part? If that's your point, then that's actually an example of how a market distortion (asymmetric information, or lie in this case) only cause short-term blips on the economy, but are then forced right back into the same general economic rules. In his case, he made the value of his own jobs lower by being a douchebag, reducing the demand for the jobs he offered, and had to raise what he paid to keep his employees.
