No, it was the 60's, 70's. (BJ first published in 1973) There was that whole journey of redemption thing, that whole man stands alone vibe. It's a good life if you don't weaken. Ever seen the Incredible Hulk live action series? You stand alone, with resolve, and your fortitude isn't your muscle strength, it's your moral strength. Black Jack just wanted people to value people more than people were valuing money. So bill them for all their money and they'll start working for life, and valuing life, rather than working for money and valuing money. Break the cycle of thinking that money is what is worth living for. It's the people you love that should be all you need. The past had a different way of thinking then the present, but they (Tezuka and Black Jack in this case) were right anyway.
