Sorting by total value of two fields in another table where ID = ID

Question

I am trying to sort two tables like this:

1 | Gang 1 | Total wealth: $100,000
2 | Gang 2 | Total wealth: $97,000

The gang structure ("gang"):

gangID, gangName

The player structure ("players")

ID, Username, Gang, Money, Bank

I want to do a query on if a player is in gang, it will count the players Money + Bank to the total wealth. However, I am unsure how to do this, and I'd really like your help.
