So the choice is between charging the current workers more and giving the retirees less. Of course when everybody only cares for their own the retirees would prefer the first approach, while the workers the second.
So, may be instead of measuring who has the biggest lobby (we know the answer) we could consider what is fair and responsible.
Here are the historical tax rates:

The taxable limit has been going up (inflation), but the tax rate has been going up as well.
That second part is plain wrong. Why should somebody put in the system during their working life 10% of their income and when it's time to get retirement ask that the current workers pay 15% to support their pension? The current workers should have to put exactly the same rate, the taxable limit should be going up with inflation and retirees get as much money that translates into. Anything else is one generation mooching off another and/or fiscally irresponsible.
