It's because the bourgeoise is shutting the door and kicking down the ladder behind them. The student protests will be drawn along class lines. The majority of students protesting in support of Palestine will be those on grants, bursaries and scholarships. So normal people good at academics or sports. The majority of those on the Zionist side will be the rich fail children there because of money, family connections, or both. By cracking down hard on the protests, the bourgeoise are saying that class mobility is dead, unless you fully assimilate to their moral values. In essence, that's the message here. Class mobility is dead, there will be no way to improve your position without fully selling out, and we are going towards a pseudo caste/feudal system.
