Well, I don't need social security, you say, because I have State Teachers Retirement. Except that's currently underfunded to the tune of 20 billion dollars. That's about $670 for every person in California. There's talk of increasing teacher, district, and state contributions to the program; teacher contributions are already higher than the withholdings for social security!
While CalSTRS points out the fund has enough assets to pay benefits for six decades, trustees want to keep the gap from widening. If left unchecked, the shortfall could grow to $170 billion over the next 30 years as more baby boomers retire.
When do I plan to retire? In just under 30 years. Dang boomers.
