Many young men tend to be financially responsible with money management immediately they're married, and this has been the doing of the wife they are married to, how she has been able to help him allocate his finances into the right places than what it were at when he was single. No wonder we see some hustling young men tend to do better as soon as they marry more than they were doing in their single life. I think living as a single man comes with many pleasurable distractions that can rip off money in an unprofitable way, a lifestyle which married life curtail.
Do you want to live with pressure to make money just to fulfill your wife's lifestyle? personally I won't.
If there's a man not working hard and looking to grow his money when he was single, it means it was his work life balance and he's happy with that. A hard working person can be seen without need to wait he's already with someone.
Different person has different character, not all people are hard worker, hence they should find low quality women instead.
