Well that's the thing, both of them aren't equal. Think about it this way, questions are like problems and these problems have to be solved. Finding the solution to a problem is far more important than actually having a problem isn't it?

On musing, questions are valued just as much as answers, but the key difference is that questions don't require you to think and possibly do some form of research before you drop it on musing. They are born out of curiosity and a longing for knowledge, with hopes that somebody else has the knowledge that you seek.

Of course musing on its own wouldn't exist if people don't ask questions so I guess that's why questions get upvoted as well, but the main aim of musing is to help people find answers to questions that they couldn't find elsewhere.

To put it simply, when you drop a question on musing, you're basically looking for help, and when people answer your question its basically like as if they've rendered a service to you. At this point, who's supposed to earn more, the person who needs a service or the person who renders the service?

I hope this helps.
