This is blunt but largely true. If you have better charisma and social skills people will naturally like you more than otherwise. That's how you end up in management where social skills often outweigh technical ability (which can be delegated).
It’s not only about management. There are basically three levers of power in any organization - relationship, expert, and role. In that order of importance. A manager that doesn’t know how to build relationships is much less effective than an individual contributor who has built both the right relationships and is well respected.
It's a double-edged sword. One of the goals of putting someone with better social skills in the management position is that they should be using that to get information they need. You can have the greatest socialite in existence as a manager and still fail because they were not able to correctly identify what is most important to pay attention to at the time. There needs to be a balance.
