Preparing for marriage takes a lot longer than 3 months.
If someone has bad midos, immaturity, or messed up priorities, a few classes on marriage isn’t going to do much.
I’m not saying they wouldn’t be useful, but the problem isn’t the freezer, or Lakewood, or not hearing R’ Tatz’ shiur, which I’m sure is wonderful.
It runs much deeper.
BTW, the population is moving to Lakewood, The fact that these therapists moved there isn’t a raya that sholom bayis issues (per capita) are worse there than Brooklyn.
