Sen. Bernie Sanders (I-Vt.) is at it again, and he's not mincing words. On Sunday, the Vermont senator took to X to declare that the U.S. healthcare system is fundamentally broken, and he's demanding a Medicare for All system that treats healthcare as a basic human right, not a profit center for corporations.

"Our current healthcare system is broken," Sanders wrote. He didn't stop there, adding, "Progressives understand healthcare must be a human right, guaranteed to all, not a source of billions in profits for insurance and drug companies."

To back up his argument, Sanders pointed to a recent poll showing that 64% of Americans support Medicare for All. His conclusion? "They're right. Let's do it."

The senator also shared a 50-second clip from his July rally in Minneapolis, where he posed a question to the crowd: "Does anybody think it makes sense that we are the only major country on earth not to guarantee health care to all people as a human right?" He went on to question why the healthcare system should generate billions in profits for insurance and drug companies, ultimately calling for a single-payer system that would "guarantee health care to every man, woman and child through a Medicare for all single-payer system."

This isn't just Sanders' pet issue. The broader debate over healthcare costs and access is heating up, with several other voices weighing in.

Sen. Elizabeth Warren (D-Mass.) has been critical of healthcare consolidation, arguing that companies like UnitedHealth Group (UNH), CVS Health Corp (CVS), and Cigna Group (CI) have gained too much control across the healthcare supply chain, potentially driving up costs. She's thrown her support behind the bipartisan Patients Before Monopolies Act, which aims to restrict common ownership of insurers and pharmacies.

Sen. Mark Kelly (D-Ariz.) has also chimed in, criticizing Republican healthcare cuts and arguing that lawmakers should focus on lowering costs and expanding coverage rather than reducing healthcare programs.

Then there's billionaire Mark Cuban, who suggests that employers might be overpaying for healthcare due to complex contracts and vertically integrated providers. His advice to CEOs? Use AI tools to review contracts and uncover hidden costs.

And speaking of AI, venture capitalist Marc Andreessen is singing its praises in medicine. He claims AI is already "a better doctor than 99.99% of human doctors," citing a report that OpenAI's GPT-5.6 had fewer flaws in its medical responses than those written by physicians.

So, while Sanders is rallying for a systemic overhaul, others are focusing on more targeted fixes, from antitrust action to AI-driven cost-cutting. The debate is far from settled, but one thing is clear: healthcare remains a hot-button issue, and the push for change is only getting louder.
