Can only the wealthy be church leaders?

It can seem sometimes that only wealthy people are invited into church leadership. Caveat-I'm a naked capitalist-make as much money as you want, spend it how you want, you owe it only to yourself and family. In fact, I think envy is as crippling as a sin as adultery, even though no one wants to talk about it anymore. 

I see a lot of church leaders as doctors, lawyers, wealthy businessmen, etc. Again, there is nothing wrong with that. In my personal, subjective view- I'd like to see a few truck drivers, cops, maids, cashiers at retail stores, gas station attendants-people with a less glamorous job-in leadership positions.  That is not pejorative or insulting to leadership. As we all know, God can qualify a retail store cashier, bus driver or a surgeon as the next prophet if He choses too. 

Joseph himself was not an educated man. He was certainly a "rough stone". Thankfully, God called him to restore the church. It's my hope and prayer that in the future we'll have some true diversity in the quorum of the twelve apostles. Not just diversity of skin color-though that is important-but diversity of background, education, and experience.
