One of the ideas being floated around is to ‘means test’ Social Security benefits. i.e., to base benefits on income and wealth. Kevin Drum explains why this is already being done at some level by the way benefits are calculated and why it would be a pointless exercise to pursue any further.

Paul Krugman also makes an important point about keeping our language on benefits clear. Using the umbrella term ‘entitlements’ in budget debates is meaningless because the economics of Social Security is quite different from Medicaid and Medicare.
