I'm calling bullshit. Post a source for your examples. Also, the ABA and the AMA agree unions for lawyers and doctors. They have a government sanctioned monopoly on top level legal and medical talent. You can't even train lawyers and doctors without the approval of those organizations. The only reason those unions get a pass on the standard union rhetoric is because they are powerful while collar unions. Nobody with any credibility is saying the AMA residency matching is a detriment to the rights of workers, for example.
My "source" was in the sentence prefacing my bullets: Before becoming a developer I worked in hotels (as a banquet manager)... In response to another comment I went into a little more detail on each bullet[1].
