This is good. I believe unions have less value in mature industries where the things the unions generally wanted are baked in, and they drive inefficiency in hiring and have fundamental control over some operational aspects. Auto industry is a bit of an example, likewise the public sector. But where there are 'new games', with no historical labour power, they are often desperately needed. Amazon, Walmart and the entire 'gig economy', fast food / service workers need unions. In 20 years, when regulatory issues have caught up around the 'gig economy' they may be less needed. A lot of the food / service economy issues could be resolved just with a good minimum wage and some basic regulations around scheduling, healthcare etc. but the US isn't there yet. So 'unions'.
