There is nothing wrong with trying to earn the most money you can. I don't enjoy working with people who don't enjoy what they are doing however.
I wonder if your manager feels the same way you feel about code, but about meetings. Maybe they wish you'd chosen a career that paid less because you don't enjoy meetings. You probably drag their working day right down by not finding meetings super fun.
Anyways, their manager can stick their opinion where the sun doesn’t shine, just OP does probably since it’s anticlimactic to express opinions like that.
