Giving a family a break on paying full tuition is for people who need help, who have exhausted all other means and have no choice but to accept it. To me this means that the husband desires to work, is searching for work and is unable to find it, or simply not making enough..
However if the women is working and the ONLY bread winner, while the husband is not working but is physically and mentally capable of doing so, Then why should families paying full tuition subsidies their children?
Then how do you justify a man sitting in Kollel all day and the women working to support their families? How can you have it both ways?
