The Jewish state will die when a two state solution dies, and Jews are overwhelmed in their own "single state" by Palestinian population growth.
So in the future Jewish Israel will be majority Haredi? Do you think secular Jewish people will be ok with that once they start imposing their lifestyle all over the place? Also, I've heard Haredi men don't work... how will Israel support itself with such a large nonworking population. Economic disaster.
These trends never last. Certainly not long enough for "economic disaster"... I'd imagine if a Haredi family has 7 kids... a good 2 or 3 probably won't grow up to live that lifestyle. They'll be moderates and secularists.
And during that time it might be that wealthier, secular, liberal families have more children. Attitudes about children and the future change.
Demographers in the 1930s were convinced America's population would peak around 1960 at like 140 million people and then begin to fall forever after that. BOOM. That small generation born in the 20s and 30s birthed 75 million babies in 20 years and reversed what had been a decline in birth rates that began in the early 19th century.
Then that huge generation became the least child bearing generation in history.
The extremes, for many reasons (many of those debatable), tend to even out.
