Cars in 1984 are not comparable to cars in 2012. There are many emissions and safety requirements on modern cars that have forced the price up. Also the reliability and quality of most modern cars far exceeds 1984 models. Most young people would not want anything like a 1984 car. Ford Pintos were cheap, problem is they exploded when they were rear ended.
Housing is expensive, but it depends where you choose to live. Hip areas have always been expensive. Toronto wasn't hip in 1984 and nor was silicon valley. In Mpls I rented a decent 2 bedroom apartment in 1986 for $550 per month, the same apartment today rents for $850. if you want to live near the "cool" people it will cost you.
