Easier for politicians to promise more from Social Security than to increase the taxes to pay for it.

It's easier for politicians to promise benefits than it is to take away benefits. Even enough Republicans went along with this, in spite of worries about Social Security's long term solvency.

Since they did this, next step should be to raise the cap on income that is subject to the Social Security tax. This would return the Social Security fund to more solvency, but it's harder for politicians to propose any increase in taxes.

Passed in the Republican House and in the Senate. Biden will likely sign it.
