Ignoring everything else the US needs, I'd love to see the US gain a public-facing union rep like Mick Lynch (UK). Someone who won't put up with the media's nonsense and is straightforward in their goals and methods for representing their union's values.

As much as hero worship can be a problem, I think such people help improve the class consciousness of the US working class and could help them realize, "Hey, we actually CAN do something to change and improve our government. Here's how."
