The LTD proposal is a joke as well. The buy up is only available with a 15% pilot group participation, so might as well consider that to be not an option to buy up.
So you are left with $5,000 a month from the company until social security benefits. What is $5,000 a month going to do today to support a family? How about in 20, 30 years? This is taxable so basically you will be living on 2nd year FO pay, hope you have a second career picked out.
If you are a CA, making $200k a year, a $5,000 a month LTD is the same as a 30% monthly payout on your salary. How many feel that 30% will take care of your family's needs for the next 30 years?
