I doubt many on HN of all places are for legally mandated unions, which are the ones that produce true cartel like behavior. Most unions maintain authority through their collective bargaining alone - to abstain from the union would mean the loss of most of your workforce, and thus you must negotiate with the union. Except if you want to call unions cartels because they negotiate on behalf of their members with employers than anyone trying to barter in business is engaging in cartel like behavior. Its deconstructive because in practice unions only exist to counteract the power imbalance between worker and employer. A cartel in business forms not to counteract power imbalance through collective action but to monopolize existing power. You might call those origin points irrelevant but they make the world of difference to me. In the absence of unions labor is almost universally exploited. In their presence, businesses are hopefully and sometimes forced to bargain on more equal footing. Thats a net benefit. A business cartel likewise exists to imbalance what was closer to equilibrium and thus is a net negative.
