Charedim are the fastest growing segment of the Israeli (and Jewish population as a whole) at some point in the near future 2030-2050 that will be the majority of the population and soon after that a super Majority (say 70% or more).
The math doesnt work, you cannot have 70% of the population sitting a kollel while the rest do the army, work , pay taxes and support the other 70% while trying to support their own families
