That’s never been proven. The blue states re the most objectively desirable states to live in with maybe the exception of Idaho and Wyoming and Florida. Blue states have more leverage than they apply.
I’m a blue state resident and will not argue the point about overall quality of life. But a quick look at net inflow/outflow rankings by state show there’s already a migration in the red state direction. There are many factors involved, but the cost of living is certainly one. Taxes are a large component of the cost of living. Increasing them on a segment of the population that has the resources to move elsewhere can only result in some additional migration. Whether that results in a net loss of tax revenue remains to be seen.
