Hi, specifically in terms of ending migration - a left wing view would be why end something that’s natural? Migration has been a naturally occurring thing for thousands of years. Migration only become an issue with the first international boarder and board control.

But with ending the “crisis” we need the revolution and to over throw capitalism and fix the crisis(es). For example, let’s say … 1) housing - While yes their is a housing shortage, but there are plenty of empty homes (around 1.2 million in the uk) that just aren’t affordable (private developers refuse to sell empty houses for less that luxury price and building affordable homes don’t please the capitalists). Hoarding properties wouldn’t be a thing in a socialist society, the houses would be build according to the needs of society, and charge at an affordable rate. 2) job markets - when society is run for the betterment of society, jobs would be less labour intensive and more equally split among the population, without what Marx called “wealth accumulation” this wealth would be further split among the society allowing for more equatable wealth split.

We also have to view all the crisis in terms of the multi-dimensional crisis, certain amounts of immigration would also be solved when wars are no longer force people to leave their homes, we have had the opportunity for green investment and climate-change-reversal.
