This "it's your fault for majoring in gender studies" meme is a red herring. There was a time in the U.S. where one parent could support a family and purchase a house while the other stayed at home with the kids. With nothing more than a high school diploma.
most people major in more 'actionable' subjects such as business, nursing, phycology, etc.
That is why poor in India is diff from poor in California. Even though to the poor in India, the Californian poverty seems like the stuff of kings. Etc.
In the 1950s, in the US, you could live on one income of a high-school graduate. Today, you still can... but you have to live a 1950s lifestyle.
But if you look at what the wealthiest (or even the upper middle class) have, no, you can't do that. If that becomes your measure of "how you're supposed to live", then no, you can't live on one income.
