One of the ministers in our government is a young (41), handsome person. He's got 17 (!) siblings and 8(!) kids. He looks well, considering his large family background.
He belongs to the orthodox religious circles which emphasize studying text (Thorah, talmudic books), over physical and worldly activities. In his case. he has studied beyond religious subjects, and got a profession in accountancy and industrial management.
The state invests a lot in families of this sort - religious with many kids (by way of alowances, benefits, stipends) without getting much if anything in return, in terms of taxes and army service. That causes great and persistent tension between the secular and the orthodox communities, and nothing good is going to come out of it.
The logo "Shivion Banetel" (sharing equally the burden of both security and economy) is constantly on the lips of the secular people of the israeli society. This will actually determine the future and stability of the country in the years to come.
