In Europe the Yeshivas had Eating days, meaning if you learned in the Yeshiva, you only ate 4 or 5 days a week and the rest you fasted.
By following that logic, if you eat 3 meals a day you are rich like we do today
They also had in most cities (except Krakow) Weddings On Friday afternoon so the Seuda merged with the Shabbos Seudah because they could not afford 2 meals.
Todays wedding are total gashmiut by the same standard
