I never said that there aren't $50,000 cars. But the masses are not buying these cars. In fact, the masses don't buy new cars period. Most folks buy used after the upper middle class decides it is time to upgrade.
Heck, I make $110,000 a year and I don't buy new. I'd rather spend my money on things that are investments... retirement, education and house (somewhat of an investment), not something that depreciates 30% its first year.
