Can’t say for sure, but I’d wager it’s because of campaign finance. Corpos fund campaigns and a pro worker 3rd party would be inherently against corporate interests. Anyone who tried to break away from the democrats would end up without any funds and new democrats would run against them with vastly more money.

It’s also worth considering that they’re probably not that popular. Most of the population are disengaged from politics and tend to just vote with the people in their communities. Text based social media tends towards a leftist bias and probably makes them seem more popular than they really are.

USPS is unionized. No cameras, Way less micro-management, and you can pee when you want to.

I just did a quick read on it on it. “Work” is the application of force over time in the direction the object is moving. Pushing a shopping cart for example is work, because you have to constantly apply force to it.

From what I’ve read, it seems that magnetic force doesn’t do work because it doesn’t apply force in the direction the object moves. Magnetic force only “deflects” or changes the direction of an object with an existing velocity. It’s only a deflection because the force applied is always perpendicular to the direction of the velocity.

To use the previous shopping cart example, picture a shopping cart that already has a forward velocity that passes a magnet. The magnet only applies a force to the side of the cart towards the magnet. This doesn’t push the cart itself, but changes the direction of its velocity towards the magnet.
