I'm surprised you'd say that.
Do you think it's wise in this environment to pay normal, 100% Social Security benefits to someone with three million in the bank?
Means testing is already being utilized in Medicare Part B premiums.
.
The increased administrative costs alone probably make means testing cost prohibitive. Economist James K. Galbraith referred to means testing as “an administrative horror show” that will make the programs more expensive to run.
Some of the problems with means testing are;
-as Jared Bernstein has said “the history of social policy leads me to worry [that] once you shift a program from universal coverage to means testing, it’s increasingly vulnerable to deeper means-testing until
it eventually becomes a poverty program which everyone wants to get rid of.”
-in order to generate enough revenue to offset the administrative nightmare means testing would cause and save enough money to make a difference, according to economist Dean Baker we'd have to means test people earning $60K. And, "Means-testing would harm seniors who already have paltry incomes. Proposals to increase premiums for 25 percent of beneficiaries, for example, could hit American seniors who make as little as $47,000,
according to the nonpartisan Kaiser Family Foundation."

4. Means-Testing Plays into Conservative Deficit Hysteria
Conservatives promote deficit hysteria because they have a fundamental hatred of government and wish to destroy the New Deal programs that have benefitted the middle class and the poor. If they were really concerned about deficits and spending, they would not support costly and unnecessary wars, monopolistic conditions, and extremely low taxes for the wealthy and large corporations.
By falsely asserting that the benefits of Medicare and Social Security are major drivers of the deficit, conservatives try to divert attention from the wasteful things that actually drive deficits.
Social Security does not contribute to the deficit. It is a well-managed program in fine fiscal condition, and there is no justification for tampering with it now. The Trustees Report shows that the program will be able to meet all of its obligations at least until 2033. If there is a tweak needed down the road, that can be
handled very simply by raising the cap, which stands now at just over $100,000.
If you are truly concerned about income inequality, raising the cap is a much better way to address it than means-testing.
