No they don't have to adopt the values of the 1930s, but there is something of wit and cruelty quite inherent in 1920s and 1930s music so it kind of suits the lyrics. Do not male jealousy and attempts to keep women 'under control' exist in the real world, so are songs about this aspect of life somehow completely off limits. In any case there is enough side and winks in the delivery of the song to suggest that the woman singer is not completely docile. Some of the dresses are flapperesque (associated with a early period of female emancipation) I suppose there was an also an element of reaction of men trying to put women back into their 'place' despite the increased freedom of dress and travel for (rich) women associated with the those times. But essentially its period-piece fun. Don't try and take it too seriously. Whether or not it gets any points is a different matter. Lets see. I have predicted 50-60 points.
