If you want to see data, we can look at IRS data:
"New York’s tax base shrank by $19.5 billion while California lost $17.8 billion as a result of workers fleeing those states during a time when lockdown measures allowed employees to work remotely, according to the Wall Street Journal.
Other high-tax jurisdictions such as Illinois ($8.5 billion); Massachusetts ($2.6 billion); New Jersey ($2.3 billion); and Maryland ($1.9 billion) also saw an exodus of workers during 2020.
The states that reaped the benefits of the “wealth migration” include Florida, which gained an additional $23.7 billion in gross income; Texas, which gained $6.3 billion; Arizona, which took in $4.8 billion more; North Carolina ($3.8 billion); South Carolina ($3.6 billion); and Tennessee ($2.6 billion)."[1]
