SS Trust Fund worries? -- just a matter of flip-flopping income streams

 Isn't the Trust Fund question just a matter of flip-flopping income streams?  My understanding is that TF bonds are cashed with income tax.

When the TF runs out, FICA can be raised while income tax is cut -- not exactly the same payers for both taxes; but for most payers no giant burden.

Raising, or eliminating, the FICA cap comes to mind.  Rebuilding labor union density even comes to mind -- flooding FICA income.

Something like a five year, projected outgo, fund could insure Congress never takes too long getting around to resetting FICA tax level.
