There's no way I was going to move back in with my parents after graduation. Once I was out of the house just after having turned 18 I was OUT. OTOH I never received any money from my parents through college either and paid for it all on my own through student loans. I had no problem at all with my parents - it's just that I wanted my independence and valued it highly.
This isn't an either/or situation. There are ways to avoid taking on a ton of debt achieving a major with difficult employment/income prospects.
I don't see an issue with some grads deciding to move back in with the parents after grad and don't knock them for it if it works for them and their parents but I also understand the desire to become independent which by definition doesn't happen if one moves back in with the parents with the parents providing support. This desire isn't due to what one thinks others might think of them, it's due to how they feel themselves.
