The message IS clear...but I don't see the same message as you. Solomon was /beyond/ rich. So was David. So were countless people that are destined for heaven(as in, Jesus describes them being in heaven in the new testament).
Those people all did some things we can see and talk about - and possibly many things we did not see, do not know, and can not talk about. At the very least, those people we know are in/destined for heaven: followed God, feared God, obeyed God.
I don't believe their being or not being rich is part of the calculus for "getting into heaven" as you said. Being rich may make you less likely to do those 3 things though, in which case you would correlate richness with not getting into heaven.
