There is no political will to fix SS, and the longer the politicians postpone it, the bigger the eventual adjustment will need to be.  
Raising the eligibility age for SS or OAS is not the same as raising the retirement age.  Many people will still retire at the same age, and live off savings, or in poverty, for a few more years.  Many of those between 65 and 70 may want to work but are not able to find work or are physically unable to.
