You have to learn to say no to pointless meetings. It's true that there are many stupid people who will try to hold them and they have to be corrected. Usually saying "I won't contribute anything valuable and nor will I gain anything valuable, so it's not the right use of company resources" will suffice. This means that you have to develop your skills so that you are not scared of acting like that (not scared of being fired). It's ok to be fired / leave a company -- the goal is to not be scared that you can't get a better job if they fire you for pushing back about meetings.
