Yeah, I didn't word it well but part of that is exactly what I was getting at in my post. In the US there's a weird crab-bucket mentality thing going on where we shoot ourselves and each other down when making an attempt to skill up. Maybe worse, if you ignore that and skill up anyway those same people will take it as a personal insult and act like you're trying to be "better" than them. "You're one of us, stay where you belong." It's a truly bizarre dynamic.
The money part is real too, though. It gets baked in early. I've had to try to shut out that nagging voice in the back of my head myself.
