Because people who promote these policies have their own vested interest. The formula is always the same: 1. You pick a minority that suffers from something, compared to the majority. The minorities usually feel intimidated by the majority, and the viral/network effects within them are much stronger. Once you get them to back you, this directly translates to political capital. 2. You find a way to offer help to them, that is seen as beneficial at the first glance, but in the long run will not solve the problem. This entrenches them, making them dependent on your help. 3. You find a party that will pay for your policy. It needs to be a relatively large group with much weaker network effects. They also need to be wealthier than the minority, so you will be seen as a nuisance, rather than a real threat. 4. You use the "*ist" label to quickly shut up people criticizing your policy and pointing out its long-term inefficiency. Because most of the critics won't have a vested interest, they won't fight you till their political death. Instead, they will quickly retreat in fear of social media outrage against them. Rinse and repeat. The minority continues to suffer, the silent majority is scared to criticize anything, the society becomes more and more polarized and divided.
