A. The answer is yes, because it has an automatic cost of living adjustment (COLA) feature. The COLA is only 0.3% for 2017, but could be 2.2% in 2018, in 1981, COLA was 14.3%!
If possible, try to postpone taking social security benefits as late as possible, because if you take social security at age 62, the benefit will be reduced by as much as 30% compared with delaying it until full retirement age 67. For every year you wait to take social security benefits until age 70, you will get guaranteed 8% return, plus future COLA will be based on that bigger benefit.

A married couple could maximize social security benefits by letting the higher earner delay taking social security until age 70, in this way, no matter who dies first, the survivor gets the largest possible benefits.
