An interesting problem. The answer is partly that there is more to life than money - and as another poster mentioned, there's really not much leisure involved. The cheaters legitimately work very hard!
Essentially, I think the Gervais principle [1] is largely true. And therefore it's fine, and from a spiritual perspective, strictly better, to be a loser. (And I don't think there's any harm in trying to find an exception to the principle - tilting at the windmill of an honestly made fortune!)
