Start with the conclusion you want and find evidence to fit it. In today's world we have mountains of evidence for anything you want to prove. Eggs, are good, eggs are bad, lots of evidence either way. Same thing for coffee. And obviously for political views too. We could spend the next year, five days a week, eight hours a day, and never stop finding evidence to support the conclusion you want. 

The way you took this news item on the minimum wage as an invitation to go into what you do with that comment, wow, does every issue lead to "my side is 100% right and good, the other side is 100% lies and evil" thinking. Jeez!

It would be useful, however, to recognize, as you do that, that this is approaching infinity. There is just as much evidence on the opposite side. And there always will be.
