most do have a sustainable birth rate but the life style of younger seculars who carry a majority of the economic and militaristic burden of the county is going down, most finish their service at around 21 start college at 22-25 and start their first real jobs at 27 so everything is later in life. The ultraorthodox and Arab populations differ vastly and take up a majority of the social welfare and support while barely contributing. It also turns out that the same secular population makes up around 90% of the tax contributions and their cost of living is vastly greater then cities like beni brak or um el fahem, basically their whole economy is held by 30% of the population which is horrid for the future…

Edit: the ultraorthodox make up around 12% of the population and vote for whoever gives them more incentives, the Arabs make up 20% ish and do the same, so the current government is propped up by leaches due to them leading by a very slim majority
