Since you're talking about 'credit' you have completely missed the point. I'm talking about making the whole team look good by making them better. That means helping team members get better. That means helping your boss get better. If the whole team looks good, guess who benefits the most from that? Your boss. And, who cares who decides promotions. If every team you end up on becomes great, you will end up where you want to be.

This also has nothing to do with a just world fallacy. This is thinking long term. Rarely can someone politic all the way to the top. In order to lead, you need the support of your team. You get that by being a great team member yourself.

Finally, I'm tired of hearing how awesome people are, but their team sucks or their boss sucks (doubly so for people working at FAANG, because the low bar is so much higher). If they are so awesome, then get out there and help the team improve. Instead it's I'm so smart, but everyone is holding me back. I'm stuck on a crappy team, etc... Grow up.
