It got crowded for obvious reason. The amended Law of Return gives the right to immigrate to Israel to children, grandchildren, and a spouse of a Jew, as well as spouses of their children and grandchildren. So, one Jewish grandparent brings in a whole big family of non-Jews. The legend of the ten lost tribes brought in immigrants from Ethiopia and Sudan. With the world instability increasing, more people will come. Not easy.
But, I think the root of the problem lies in a very unhappy timing. The changes of the world after WWII world, the Cold War and plus, certain inertia. The state of Israel was created precisely when the British colonial world was collapsing. It is as if you put in a tiny bead, Israel, into an oyster clam, the Arab world, and leave forever. Immediately, the area changes, monarchies fall, charismatic opportunists come to power and the parties on both sides of the Iron Curtain make their bets. Had the Brits stayed longer, all would have been very different. JMO, many might disagree, but I believe, tragic timing. And now, 75 years later, the world has radically changed, but old commitments stay.
