They torpedoed Medicaid already. Is this precious program next?​

Medicare turned 60 years old on Wednesday. Former U.S. President Lyndon B. Johnson signed it into law on July 30, 1965, giving seniors a guarantee of health coverage that never existed before. Prior to Medicare's enactment, it was nearly impossible for older people to obtain health insurance, as they were considered a "bad risk."

Medicare provides universal coverage to Americans over 65 years of age. The law created Medicare Part A as a national hospital insurance program. Part B is a voluntary program for doctor visits and other medical services. Medicare Part C is another name for the privatized, for-profit version of the program called "Medicare Advantage." And Part D is the prescription drug program enacted in 2003.

The Hospital Insurance portion is funded through workers' payroll contributions. At the signing ceremony in Independence, Missouri, LBJ said, "Through this new law, every citizen will be able, in their productive years when they are earning, to insure themselves against the ravages of illness in his old age."

Johnson paid tribute to former President Harry S. Truman, presenting him with the very first Medicare card. It was Truman who, 20 years earlier, had proposed a form of universal medical coverage for the American people.

LBJ quoted Truman's remarks from the 1940s:

Millions of our citizens do not now have a full measure of opportunity to achieve and to enjoy good health. Millions do not now have protection or security against the economic effects of sickness. And the time has now arrived for action to help them attain that opportunity and to help them get that protection.

It turned out that the time had not yet arrived. Truman's proposal failed to gain traction during a time of retrenchment from the expansions of the New Deal, and a Republican majority on Capitol Hill which he famously labeled the "Do-Nothing Congress."

President Johnson's determination to enact his Great Society agenda (of which Medicare was a large part) and sheer political muscle—not to mention solid Democratic control of Congress — pushed Medicare (and its sister program, Medicaid) into being.

Naturally, Medicare faced strong opposition from conservatives. None other than Ronald Reagan made the ludicrous prediction that if Medicare were enacted, "You and I are going to spend our sunset years telling our children and our children's children what it once was like in America when men were free." Sixty years later, we are no less "free" because of Medicare. In fact, having guaranteed healthcare makes seniors and people with disabilities (and their families) much more free — from disease, from worry, and financial ruin.

Today, 68 million people rely on Medicare for health coverage, including 12 million who are dually eligible for Medicare and Medicaid.

Medicare isn't perfect: The for-profit Medicare Advantage (Part C) program is extremely problematic (see below). The Medicare Part A trust fund will become depleted in 2033 if Congress fails to take action to strengthen it. Traditional Medicare still doesn't cover basic hearing, vision, and dental care — which we have been pushing for many years. But most concerning of all, President Donald Trump and his party have spent this 60th anniversary year actively undermining both Medicare and Medicaid.

The "Unfair, Ugly" bill that Trump signed earlier this month slashed nearly $1 trillion from Medicaid, which will strip health coverage from an estimated 10 to 16 million lower-income Americans. The new law — projected to add some $4 trillion to the national debt — could trigger cuts to Medicare down the road.

Meanwhile, the Trump administration is recklessly taking steps to privatize the entire Medicare program. It has announced a pilot project to involve private companies in conducting prior authorizations for care in traditional Medicare. The administration, under Health and Human Services Secretary Robert F. Kennedy, Jr. and Centers for Medicare and Medicaid Services Director Mehmet Oz, also has announced a plan to automatically enroll new Medicare beneficiaries in the for-profit Medicare Advantage (MA) program — a huge gift to the multibillion-dollar insurance industry at the expense of patients.

The problems with Medicare Advantage (MA) have become legendary. Enrollees are basically put into health maintenance organizations run by insurance giants, with limited networks of providers. Unreasonable denials of care are rampant. Patients who become disenchanted with MA plans often find it nearly impossible to switch to traditional Medicare. Meanwhile, some MA Insurers have been overcharging the government for their services and ripping off taxpayers. (Several of these companies are currently under investigation.)

We are watching to see if the Trump administration, which talks a good game about lowering prescription medication costs while simultaneously doing favors for Big Pharma, will honor the provisions of President Joe Biden's Inflation Reduction Act, which made myriad patient-friendly reforms to the Part D drug program — including out of pocket caps for beneficiaries and empowering Medicare to negotiate prices with the industry.

The bottom line is: Let's not allow President Trump and congressional Republicans to shred one of the greatest legacies of LBJ's Great Society. We and our fellow advocacy groups are pushing back — and so is the grassroots "Hands Off" movement. But we don't want to be fighting this same battle every time Medicare (and Medicaid) mark an anniversary when we should be purely celebrating.
