The point is that young workers starting in the 90s were put in a position of having to make up for the prior generations who weren't contributing enough.  In addition to paying for their own future CPP.  That isn't to put blame directly on individuals but rather governments of the day getting elected and staying in government on unrealistic promises or poor management.  Which in turn put the blame indirectly back on the individuals who continued to vote in those governments that passed the buck on to future generations.

As to your comment about saving enough - most people are perfectly capable looking after their retirement needs without relying on CPP.  Whether they choose to is an entirely different matter.
