Unions, when invented, were a great thing. That anybody thinks there's still any good unions around proves P.T. Barnum right: There's a sucker born every minute.
Of course it's not all sunshine and rainbows, there are all kinds on smaller stupid things the unions insist keeping alive as they might worsen the benefits of some workers (even if they would benefit some other workers).
They also have managed to make themselves seemingly irrevelevant, as many younger workers believe all those existing benefits are rights that cannot be taken away.
