You are assuming that Borsalinos go along with luxury apartments and leased cars. They usually don’t.
I don’t know precisely what the cost of living in Lakewood is, but it starts at less than 50k, and anyhow, in the vast majority of cases, the girl’s father does not undertake to fully support the young couple regardless of income or expenses. It’s usually a set amount, and far, far less than the numbers you’re using.
