the idea is simple - similar to the way that the government gives benefits packages to new immigrants and to others to help them out when they are making a new start in Israel with few contacts and resources to fall back on and little or no family to lean on, Porush is proposing that secular Israelis who become frum are making a similar start and have often left the embrace of their families and may have nobody to lean on for support and assistance. Porush thinks the government should help chozrim bteshuva just like it supports some others starting off on their own.

there are definitely some, maybe even many, extreme in which a chozer bteshuva is doing it all alone, with his or her family providing nothing but rejection, leaving his circle of friends and having no resources, but plenty (and no, I dont know numbers) become religious without giving up, or being rejected by, their families and friends. I am not sure the new beginning with no resources or support is quite the same for most people becoming frum. Additionally, a secular Israeli becoming frum generally has an education and job or a business - it is not like someone moving to a new country that has to learn a new language and look for a job, along with making new friends and social circles.

Regardless, today, Arik Bender of Maariv just reported, the Knesset Committee for Legislation just voted down this proposal. 

I remember a little while back someone proposed a similar law that would grant these benefits to people becoming not religious - chozrim bsheilah. I dont know what ever happened to that proposal.
