FDR, whom a lot of you probably admire on this sub. Stop voting for Democrats (I certainly do not call on you to vote for Republicans).
https://en.wikipedia.org/wiki/Stabilization_Act_of_1942
The Act authorized and directed the President to issue an order stabilizing prices, wages and salaries to the levels they had had as of September 15, 1942,[2][3][4] and to issue additional regulations related to the Act.[5] The Act excluded from stabilization “insurance and pension benefits in a reasonable amount to be determined by the President”.[6]

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]
