Correct. Non Jewish professional women almost never have kids before 30 (or 35+ if they are very career oriented). And even then they only have a couple max..
Jewish girls are educated to observe the Torah which commands a man to have at least two kids ASAP.
This has nothing to do with chulent. It's just reality. An apple is just an apple.
-1 on the first statement. Plenty of non Jewish professional women who have kids before 30. I know people like this that I work with, that I went to school with, etc. You don't strike me as a guy who has any non-Jewish friends. So your statement is based on a sample size of what? 2 people? Maybe 3 if you're one of the more open minded people in Lakewood.
As to the second statement - *facepalm*. You do realize that there are plenty of respectable Ravs who give heterim to not have kids right away, right? Reasons include financial, career, etc. Not everyone holds that you'll burn in hell if you don't try to set a record for the amount of kids you can possibly have between the age of 19 of 35.
