"Seems to me that Parliament is dominated by the fruits of our "rounded and rewarding society"."
Just the opposite; Parliament is dominated by PPE grads and doesn't have much in the way of other humanities. The result being a badly skewed view of the world.
A similar thing happened in the Soviet Union about 50 years ago. Stalin more or less abandoned education outside of STEM; social science was essentially deemed 'finished' (because Marx was right, so why bother doing research in it anymore). The result was a huge wave of engineers being trained in the late 20s and early 30s, and no-one with any soft skills - so they thought you could run society like a machine. When these guys came to rule the country in the 1970s and 1980s, the whole thing fell apart.
Basically, you want a good mix of people running things - STEM guys to understand technical stuff, humanities grads to understand people. Banning one set or the other basically ends in disaster.
