Who said getting rich doesn't matter? It is what matters to you that is important, for all values of you. Being rich didn't matter to Ghandi. If you do what you love, you are likely to be happy, even if you are not rich. If you just love money, I suppose doing what you love is equivalent to getting rich.

Why does the thought that many people may consider Ghandi's life to be more meaningful than your own upset you so much? Boy, you have an ego...

For the record, Ghandi's accomplishment is not "putting his name in the history books", but rather "being spiritual and political leader of hundreds of millions of people and having a great impact on their lives".

Even Indiana Jones has a teaching job.

I don't know if it's fruitful to focus on specifically. I think the parent may have meant, "Gandhi is an example of someone who accomplished great things and did what he thought was important, but it didn't make him rich. Would you want to be in like Gandhi in this general regard?"
