And the more they do this, the faster they drain Medicare’s trust fund straight into their money bins.
This is the misconception that feeds our nation's corporate predation on its citizens. There is no "trust fund" that contains any actual money. That isn't how bonds, or federal spending in general, work.
Both Medicare parts, A and B, are funded by spending approved in the non-discretionary budget, but only part A is "in trouble" because it has a "trust fund" attached that can be depleted. Treasury cannot hold "money" in reserve for future spending. It can only delete money from the private sector with a promise to repay at a later maturity date.
A sovereign currency-issuing government cannot become insolvent in its currency, and that extends to any legal programs approved by Congress, such as Medicare (and Social Security), regardless of past or present "revenue" positions. Interjecting a "fund" composed of Treasury instruments only gives cover for reducing the spending power of labor over lifetimes and, eventually, destroying the program they were intended to protect.
When FDR argued for the 1% payroll deduction for Social Security benefits to give beneficiaries a "legal" claim to them he couldn't have foreseen how that would be expanded to fuel efforts to destroy it and the Medicare program that would be added later. One of the architects of that program, Beardsley Ruml, Chairman of the New York Federal Reserve bank, did have a premonition of such and wrote a paper in '45 titled "Taxing For Revenue Is Obsolete" as a warning of future events.
Between the two programs, the taxes drawing down the middle-class spending power in the economy account for the largest transfer of wealth upward in world history. They are neither needed nor used to provide benefits. Both should be eliminated and both programs should be greatly enhanced if we are to continue our claim to greatness among first world nations.
