Is there a future as a bellboy in a five-star hotel?

Why do people nowadays always ask if there is a future?

If you don't have the heart to make progress and only work as a porter all your life, there will be no future, only a fixed but not much income. Maybe you can't support your family.

But if you are willing to teach yourself, you can go up in the job of a waiter, or learn something, and then jump into a better job. This is the future.
