Your answer is incoherent to the point I made.
Of course, a radical goal is attaining universal coverage, partly because it is harder to reverse. And despite the idea that social security was attained in one big bang in the 1930s, the coverage of more employers and extent of benefits was expanded step-by-step over the decades. It was only in the 1950s that coverage was expanded beyond a limited number of jobs in commerce and industry, and only 1956 was disability insurance added.
Similarly, minimum wage had relatively limited coverage in its initial version and only slowly was extended to most employees in the country. Both programs were expanded only incrementally from a limited number of employers to most employees in the economy. Specifically, minimum wage only applied to the largest employers in retail initially, much like the fair share bills, and slowly over the years was extended to smaller retail establishments.
Universal programs are the goal but none in the United states were ever created wholecloth covering all workers in the economy. That was a hard incremental set of campaigns.
Why people can have the ahistorical delusion that universal health care can ignore that pattern is beyond me? A campaign for single payer would defy all previous history around both social security and minimum wage laws that always required incremental campaigns to achive universality.
