Define comfortably. Some people would not be comfortable with a spacious home with a room for each child, central air conditioning, multiple cars, vacations, ability to pay full tuition for yeshiva and college, going out to restaurants, buying new clothes, etc.
Some people are quite comofortable with beds for each child, adequate access to transportation to get to school and work, ability to finance education even if it involves creative use of scholarships, enough food to eat, ability to afford respectable clothes even if some of them were bought second hand and have been patched.
Seventy-five years ago, most frum Jews would be comfortable with a roof over their head, enough food so they weren’t starving, and not having someone actively trying to kill them.
Of course religious fanatics hold by: “????? ???? ???? ?????”
