“Sure” Of course not! It is impossible to be sure.
Lets back up.
whether raising the minumam wage is good or bad for the ecnomy, or for the lower class for that matter has been debated for decades. Leading economists are torn on the issue. I am not claiming to have the definite answer
In your OP you asked a question “I don’t understand the rationale behind raising the minimum wage, doesn’t that make things more expensive?”
I explained why your assumptions were an oversimplification. I am not saying raising the minum wage is necessarily a good idea. I was just explaing the other side, and pointing out why your assumptions in the OP were wrong even if yoru conclusion isnt necessarily wrong.
Incidently the forbes article you cite does not say what you said. You claim increasing the minimum wage would increase the price. This is not at all what Worstall says.
