"Eg their figure 2 is that infamous misleading graph that I commented on in"
If it's so infamous, do you care to point to something explaining what is wrong with it?
"They also seem to imply that minimum wage legislation is good for poor people."
I wasn't discussing this point, but agree that it's mixed.
"Figure 9 seems to forget that correlation ain't causation."
Figure 9 is just data. Sure, the explaination that goes with figure 9 talks of it as causative. I haven't read the journal article that data comes from, so I can't objectively say if there is a causative mechanism in that study that supports the text or not (can you?). That figure isn't really part of what I was discusing, although it does demonstrate the increase in top earners (not as well as charts comparing it to the changes for other labor groups).
