1. I'll admit, 80% was an exaggerated number but it still stands that teenagers are the biggest demographic of minimum wage workers. That first graph just seems odd to me.
Less than 50% are teenagers. And this ignores all the people making a bit above minimum wage who will see a wage hike if the minimum wage is raised.
2. I posted his article because some of his arguments were on point. He is also far from libertarian if you actually read his blogs and simply dismissing and insulting him because you don't agree with him only makes you look bad.
He calls himself a libertarian. And I said that as a libertarian, I wasn't surprised he ignored empiricism since that's their thing. Being one in an of itself is not what I attacked him for, I attacked him for ignoring data and only picking out 1 single (and mostly discredited) data point to back up his argument.
3. I never said it will hurt the poor or affect unemployment. I said that raising the minimum wage doesn't do much for the poor beside helping maybe the few. Your graphs are right that a lot of people will be affected by it but that does mean it will affect the poverty line. There are so many other factors involved with increasing wages that it will overall have a net affect on poverty.
Arguing that is won't have much of an effect on poverty has been completely unsubstantiated and really seems odd given what the empirical data says. Since it doesn't touch employment or affect prices much, what can it do besides help?
Furthermore, most recent research, when analyzed properly, comes to this conclusion. In fact, Neumark's own recent research came to such conclusion (only, he never published it in his paper but the data showed it).

According to Dube's analysis of studies and his own, a 10% increase in the minimum wage reduces poverty by around 2.4% (Neumark's work showed it at a higher rate of 2.9%!). I don't think that's insignificant and it matters.
In fact, many economists are pretty sure the 70s poverty was kept from being higher because of the minimum wage:

This of course still helps people not in poverty but below the median income, as welll.
Raising minimum wage is not the supposed "fix-all" that you think it is.
Now this is a straw man if I ever saw one. At no point did I indicate the minimum wage was a "fix-all," I merely countered your assertions (and linked article). There are numerous approaches we must take besides the minimum wage (such as increasing the EITC, increasing the social safety nets, increasing taxes at the top, etc) to go hand in hand with the minimum wage. It is but one tool but a tool that does work to some extent.
