As I understand it, welfare is a government subsidy for those who have no job.
The money that avreichim get (recently downgraded to 720 NIS (less than $200) monthly for Israeli’s – less for Americans) is a stipend given to all avreichim regardless of other income and family size.
The property tax discount is municipal and has nothing to do with the government.
There is a small additional subsidy for large families with no car or job that adds up to approximately 1300 NIS (around $350), but it is very difficult to qualify for and I don’t know many people who do. It is also extremely unreliable and changes often.
