There will be many explanations. One explanation not seen here yet: People working for companies who pay are more likely to be well paid and both of (a) technically competent and (b) having empathy and some amount of charm as qualifying criteria to get that well paid gig. It's no slam-dunk but it's more likely. People who work for organisations who don't pay are likely to be paid a little less and include some who are working a second choice gig because of some deficiencies in (a) or (b) or both. (L. is great but difficult to work with and we'll never find someone like that to hire to replace them.) As individuals they may improve their abilities in time, possibly dramatically too. The young, arrogant hotheads, sheesh. None of us were ever like that. Obviously... The paying can be a fuzzy select for kinds of people who behave in particular ways rather than the paying itself causing particular behavior in a given person.
