Private companies decide how much people will be paid and all they are obligated to do is pay minimum wage after that people are paid whatever the potential employer offers and if they accept the job its making a contract that says you agree to work for X amount of money even if it is far to low. The government also does not set mortgage rates the banks do so there really is nothing government can do. The bellow average pay in Israel is a problem thats goes all the way back to 1948 possibly its a result of the fact that zionism was based on socialism and so everybody was earning the same kind of money and there were no rich and poor, because government was the biggest employer and the Shekel was a very weak economy and the country didn't actually produce all that much to export. Then over the years the country developed but pay didn't stay inline with wages and when the private sector became the largest employer employees also had less influence with employers because its easy for unions to take on and negotiate with the government than it is with a private company where the only thing that matters is profit and companies are not going to sacrifice profits and volunteer pay their employees out the goodness of their heart.
