Ah, well, that’s a dumb point then. The article is silly, I’ve been saying that from the beginning. But again, your expectations for it are silly also.
And if you mean FDR was categorically wrong because minimum wage has the word minimum in it, you are playing more linguistic games and are frankly just wrong. “Minimum wage” means the lowest financial compensation allowed, not the minimum number possible (which would basically be slavery). And by his definition, the intent was to provide a decent life to all American workers.
On the other hand, if you mean that in your opinion a full time worker in America does not deserve to live a decent life, then you are morally wrong. On the contrary, a business that can’t afford to provide a decent standard of living for its employees does not deserve to exist. Though that I suppose, depends on the value you place on human dignity. If you don’t think your fellow Americans deserve a decent life, then we simply don’t see eye to eye, and as per the golden rule, you are not worthy of dignity or respect either.
