Bad conduct leads to richness?

Some people, althought saying that following the Buddhas teaching, but maybe do not have much trust or understandig into cause and effect, kamma, saying that richness and success comes from no fear to do evil. If that is the case, why are not all people who have no virtues, no Sila, rich, following their arguments pattern? Isn't it not merely because still having some merits that the downfall does not arises accurate, if one conducts wrong, thinking it will not fall to me? What's the effect of Sila, virtue, on wealth and success? *(Note: this is not given for trade, exchange, stacks, entertainment but for release from this wheel)*
