The impending disaster as Labour dials all the Tory idiocy up to 11 is what will hopefully create the political space for an actual small-c conservative party, likely some messy mishmash of nationalists, classical liberals and old-school pre-woke former tribal labour supporters.
The not-very-ideological “tribal voters” (which face it is a large chunk of both Labour and Tory voters) will only be up for grabs when it become impossible to pretend the old tribes still exist. Most Tory tribal voters have got the message, and some Labour ones as well. The next few years will convince what remains.
It will be a ruinous, horrible intermediate period (in the Egyptian sense of the term). Close to nothing Labour does will make people’s lives better, and as Labour gets desperate, they will become ever more rapacious as they try to fund various doomed-from-the state schemes (such as the nationalised energy company, which I imagine will quickly become the British Leyland of our time. As a result, many with movable assets will indeed move them and themselves elsewhere until it becomes clear how things will shake out in the medium to long term.
