And never has been. You look at history with a granular enough lense, and it all starts sucking more and more, including “great progressive victories” like the New Deal (excluded sharecroppers, constructed the American warfare State by building bases mostly in the reactionary South, helped neuter union radicalism through official recognition via the Wagner Act, created the juncture of employment and health insurance via the Stabilization Act of 19421, and a host of other issues). Labour has always sucked (Ramsey MacDonald's government led Britain into World War I). Labor unions in the official sense suck dick (the Teamsters endorsed Ronald fucking Reagan). The German SDP is neoliberal, but so are the German Greens.
One consequence of the wage stabilization under the Act was that employers, unable to provide higher salaries to attract or retain employees, began to offer insurance plans, including health care packages, as a fringe benefit, thereby beginning the practice of employer-sponsored health insurance.[12][13]
