The effect will be many-fold:
- Increase in employee satisfaction and quality of life. Those who leave will have a much lower cost of living and can enjoy the extra money. Those who stay here will be here because it's worth the money to them.
- Lower real estate costs for employer.
- Reduction in employment and resulting housing demand in California.
- Increase in tech populations in other areas leading to networking effects and economies of scale, making them more attractive to work at, further reducing housing demand in CA.
- Better distribution of tech talent and benefits in the country, reducing anti-tech resentment and political backlash.
- Loss of (tens of?) thousands of dollars in income and sales tax revenue for CA, per employee, imposing a real fiscal cost for not implementing housing supply friendly policies, and creating proper political incentives.
- Loss of demand for local businesses and services, leading to a negative feedback loop to reduce local opposition to increasing housing supply.
- Opportunities for tech and other businesses that embrace and help facilitate remote work.
- Tech companies being closer to average people, aware and solving their real world problems instead of SF techies' scooter and/or food delivery needs.
Stuffing more employees into the Bay Area and throwing a few bucks to YIMBY is not a serious solution, it's a fig leaf.
