One of the upsides of New York Mayor Zohran Mamdani’s $70 million state-run supermarket project is that it allows rational Americans to watch socialism fail in real time. 

Mamdani Marts promise to provide 30% discounts on core grocery items, which means they’ll be heavily subsidized by taxpayers. Most grocery chains already operate with a slim 2%-3% profit margin, and that’s with the benefit of highly efficient global supply chains and bulk orders.
