Monetary Tsunami In America!!

You are throwing around bad numbers.Essentially no households spent 30K on a home computer in 1970. Families simply did not buy home computers in 1970. In the mid 70s computers cost around 1000 dollars. Ten years ago people spent approximately the same thing on a home computer that they spend now. They just get a better computer now. The computers I had in the early eighties were all well under 1000 dollars. They just stank (TRS-80, Coleco Adam, Sinclair Z81, Commodore 64).

I don't doubt that you sold computers for those prices, but I don't think those were average prices. I would not spend 1000-1500 for a computer, but people who want bleeding edge stuff still spend that much and even more now. I've never spent $1500 for a computer and I've had home computers since the early 1980s.
