From Marketwatch:
Social Security should be able to pay out full benefits until 2035
without any intervention, but a proposal by Sen. Bernie Sanders would
extend the life of the program for 75 years, chief actuary Stephen Goss
said. ...
The Social Security Expansion Act aims not only to pay out full benefits
but, as the name implies, to bolster the program. Under the proposal,
Social Security would provide an additional $2,400 in benefits to each
beneficiary every year. The program would also be linked to the
experimental price index for the elderly, or CPI-E, instead of the
consumer-price index for urban wage earners and clerical workers, or
CPI-W. The switch would change the cost-of-living adjustment to align
more closely with older Americans’ spending.
The proposal calls for two new taxes: a 12.4% tax on investment income
for individuals earning $250,000 or more per year, and a 16.2%
net-investment-income tax for specific business owners, including active
S-corporation holders and active limited partners. The proceeds of the
latter tax would be divided between the retirement and disability trust
funds and the general Treasury fund. ...
This isn't happening, at least not now. There wouldn't be a majority in the Senate for this and the House is under the nominal control of the GOP. I mention it because it's an honest attempt to deal with the problem, unlike ridiculous Republican claims that they want to "reform" Social Security, without raising taxes or cutting benefits.
What I love seeing in response to proposals like this is the cynical argument that it does no good to raise taxes on the wealthy. They'll just use tax tricks to avoid paying the tax. Sure. So why do these wealthy people employ shills to spread the cynical argument in forums like this? Who else but shills would spread that sort of garbage? Of course the wealthy would pay more under Senator Sanders' proposal. That's why they fight it with such vigor.
