Could a union be run as a direct democracy? Instead of a strike fund just verified segregated savings? There are much better tools for group discussion and voting. I feel like most employees would benefit from some form of collective bargaining as most employers present boiler plate agreements where your only choice are yes or no. Edit: on second thought you'd probably get a lot of protectionist, xenophobic policies. Bye bye h1b, hello arbitrary certification requirements. The incentives of those in the union are for anticompetitive policies. I'm not sure how this can be avoided.
