One is much easier than the other. To be fair, OP didn’t use the “too busy dedicating my life to local government activism” excuse. IMO one way you vote for change is by controlling what you can directly control. If the difference between having kids or not means moving to a more affordable area, then those who really would rather have kids will move. This will have the largest impact to the one who moves out of the area, of course, but it also has an impact on both the old and new hometown. I’ve seen this first hand as many are migrating to my city in the wake of the pandemic. They’re finding a better lifestyle for themselves while house prices in my area have risen 25% and still rising.
