To gain some insight into the problem, I would recommend Jame’s Mitchner’s The Source. The book theme is just the problem you have noted that has happened for thousands of years
This is the book that basically describes why Jews take a degree of pleasure making life hard on themselves in order to connect with god?
Maybe that is true maybe it is not.
Statistics show the more the Jewish people follow the Torah they more right wing are. Orthodox Jews vote mostly for right wing. In other words the book doesn't match with these statistics.
It would seem to me it is just the other way around the less they follow their religion the more they vote in those that hate them which makes it harder for themselves.
