There is no influx of out of staters moving here. You can trivially debunk this by looking at Vermont's population in the census. From July 2021 to July 2022, Vermont's population increased by less than 100 people. A few thousand moved here one year, and everyone freaked out about it, and continues to freak out about it, despite it being less than 1% of the total population. Since then, it has returned to flatline.
