Yes, in that regard, the cartoon in the specimen is inadvertently revealing. The actual 50s-style husband did not have to work two jobs so that his wife could stay home. That the male figure in the cartoon accepts that as the price for having a wife who will stay home and raise the kids is a tacit admission that we mostly do not live in an economy where that can be done any more, even if both parties were open to the traditional roles of breadwinner and homemaker, and the traditional gendering of those roles. If (as various posters have indicated) this is a little snippet from the contemporary tradwife ideology, what that ideology is nostalgic for is not just the division of roles, but for economic circumstances where one wage-earner, working one job, could provide for a family. It is not, in fact, the "ultimate flex" for the man in this cartoon to have to take on two jobs; it is. rather, a sign of one of the ways that the middle class has been impoverished, weakened, since the 50s.
We work our way outward from that to the presence of Musk in the image. When he took over Twitter, he fired a bunch of people, just announcing that the remainder were going to be more "hard core" in their work habits (i.e. work the equivalent of two jobs for the same pay--for nobody's benefit other than that of Musk himself). The entire image is a fantasy of Musk's and it doesn't have to do primarily with gender, but with class. It's promoting the "hustle" culture that we discussed in the Lying Flat thread, whereby "job creators" squeeze more and more value out of the work of their workers. It promotes that culture by connecting it with manliness (flexing, hard work, having a big-bosomed wife). But the message here is only indirectly about gender. The core message is "work two jobs."
The two figures in the cartoon need to band together to strangle Musk. Then eat him. If they prefer traditional gender roles, then the man can strangle Musk, and the woman can cook.
