I am not really sure what the prosperity Gospel is.

I think it's probably a superficial understanding of what God wills for each of us. 

So in that sense, I don't believe in it, but believe in much more than a mere temporal prosperity Gospel. 

I do believe that God wants our absolute good at each moment..and with our cooperation, He can bring it about.  He can draw us closer to Him, which is  our absolute greatest good.

This doesn't mean that we won't have troubles and difficulties....but these too can be converted into great good, not just temporal goods but eternal good for others and us. 

So net..the prosperity Gospel is probably a lightweight/temporal good focus..and this faulty.
