Company Stiffs Former Employees by Excluding a COLA increase from Pension Plan - Title Not Divulged Nationwide Employee Review

I have a number of pensions from various companies I worked for during my career. Unlike Social Security retirement and all other pension plans I am eligible for, Nationwide excluded any COLA benefit from its plan. How could a company expect a former employee to exist on a pension that was calculated when the employee retired, say 67 or 68, but could potentially be paid until the employee dies in his 90s? It certainly is cheap for a company not to give an annual cost of living increase on its pension plans unlike Social Security and the retirement plans of most employers. No wonder Nationwide charges one of the highest premiums for its insurance. It ought to be ashamed of its actions, or lack thereof. I am sure officers with the company don't have the same issue with their pension plans.
