Now where do I start?
1. The "Luxuries" you speak of are pretty much Cell Phones, cable tv / Internet and eating out once a week. These are a drop in the bucket next to the cost of a car/house/college education. Get rid of all the luxuries you want, it won't make up for the 40 years of declining wages while productivity has more or less doubled.
2. I like this one: "learn a practical skill". Reminds me of a neighbor of mine who'd been to night school 3 times and each time seen her new career outsourced. What you really means is "Somehow develop a significantly higher IQ as if by magic so you can get the STEM degree that you couldn't get when you were 18".
3. The working class doesn't get to pick where they live. It's expensive as hell to up and move. You live where you're born and hope for the best. If people could just move somewhere that's better there'd be no 3rd world countries.
4. See Point # 1.
5. See
this. Specifically the chorus ("Turning 30, 40, 50 gotta move in with my Parents...").
Fuck the American Dream. It's a bill of goods we've all been sold.
