Apparently 1, and you need to ignore all the ones that are executed well.

How many times must others get it right before you'll consider your own execution to be poor?

Well in the US we can only really vote on two opinions.

The 'left' argues for unions based on the concept. The 'right' argues against them based on their execution. So we go round and round and round and round because neither is willing to consider or admit that we might be talking past each other.

Makes for great web traffic though.

I don't understand how this is remotely relevant.

The point is: many (most?) first-world countries have unions that work well overall. Same with police departments.

What you're describing are putative reasons why the American execution is a failure.

So those proposing having unions in the US need to explain why this implementation will suddenly work differently than all the others in the US.

Sure, I'll freely admit that unions have worked very well other places, but the US seems to blow it every darn time. Why would this time be different?

Software engineering has this culture of innovation, invention, disruption, and reimplementing everything from taxis to space travel to payment systems to currency to food from scratch. Why couldn't they attempt to do the same to labor relations.

Why assume that the day after a tech union is invented, suddenly you're stuck with a massive clanking bureaucracy that's identical to the ones that were formed in very different industries many decades ago?

I think the burden of proof is on those saying, "This time it will be different."

Well, why don't we apply the scientific method and try it out! This industry was built upon experimentation and radical thinking.

Unionization is much more of a social experiment than a technical experiment.

And what is ridesharing, house-sharing, cryptocurrency, or social networking? Or open source software for that matter? As software eats the world, technical innovations are creating social situations that have never existed in the past, creating social experiments whether intentional or not.

I guess we'll find out: https://kickstarterunited.org/

The democratic left absolutely does not want unions outside of government which is probably the worst place for unions in general
