If these where the attributes to getting rich most people around the world would be rich today because many are unbanked and not married & unfortunately the topic at hand is not true.
If marriage stopped some one from getting rich then not everyone will be cursed by it, because AFAIK marriage is a blessing which kind of opens new doors of opportunity that were sealed off. If everyone was in support or against the motion a poll would be ideal to avoid one group being bias.
Unfortunately wrong marriage is what OP should have including instead of talking as if marriage is entirely bad, wrong marriage can bring so many disaster into one's life, is can close doors to all flourishing blessings, I pray we don't make the wrong choices
