From that chart, we in turn paid more than our predecessors. Not sure what your point is other than government keeps steadily increasing the % of money that they collect from us. They seem to think they can use that money more intelligently than we can ourselves.
Admittedly, it is tough to 'take back' promises made and paid for. Just look at the charged level of the public pension threads. It's not something many politicians are eager to take on.
For me, a start at least would be to start winding down the future promises and the future collections. Every policy should require a one-page, understandable to the common man, 'mission statement' of just what it is designed to achieve. I've asked a few times on this forum, and no one has been able to explain just what SS is supposed to do. If you think about it, it's a contrary mess of counter-intuitiveness:
Is SS to provide a 'safety-net' for Grandma?
OK, but why promise payments to people who don't need it? And why collect and pay-out based on a % of salary? The more you make the less help you should need, but the whole system is backwards - the more you made the more you get. The collection system is a combo of 'flat-rate' and 'regressive', the pay-out is steeply 'progressive'. It's a complex mish-mash. Add to that other social programs for the elderly, and who knows what really goes where?
If I were king, I'd completely un-wind SS going forward and privatize it (to encourage saving/education to help keep people off the dole in old age), with a possible government sponsored annuity system to safely spread 'longevity risk'. I'd replace it with a safety net system to provide for those who need it. Why mix the two - it just obfuscates the whole thing?
That's a start.
