Well sure, but that's already obvious and kinda to be expected. You've already got a few heroes (like Ms. Mount or whatever her name is...that growing woman) that are clearly mostly in the business for prestige. But the majority of the main cast have decent enough motives, which is refreshing for me. The main kid just wants to be a hero; the "why" isn't obvious yet, but so far he's mostly just a selfless kid that wants to save people even at the cost of his bones. His probable love interest *is* trying to get money...but the money is to support her family, which isn't the worst motivation. Their friend, the speedster, wants to continue the family tradition of hero-work and has been shown to be quite caring of his fellow students.
Take One-Punch Man as a counter-example. The main character, while occasionally displaying genuine heroism, is primarily in it for two reasons: fame & fortune, and the hope of eventually having a real, no-holds-barred battle. His disciple in the beginning was all about the pursuit of vengeance (he's mellowed out a bit since then). The vast majority of low-ranking heroes - and more than a few of the high-ranked ones - are clearly in it for the money, many fleeing from danger unless they are either cornered or convinced they can handle whatever the danger is. I'm certain there are more examples.
Now, I do like OPM quite a lot, but at the moment I'm enjoying MHA for somewhat different reasons. It feels a bit more...pure, I guess.
