Well I was talking about trickle-down *technology*, not economic policy. Marantz's first customer was a near Eastern sheik; hardly anyone else could afford hand-built cost-no-object high end components. Sequerra's Model 1 Tuner was $2500 in 1975 (almost $10K in today's money for an FM tuner!). Within a year Kenwood had one based on the same principle for $599. In the '40s the IBM CEO famously said that there might be 7 customers worldwide for a computer. At $7M per ($76M in today's money), he was probably right, but today we can get computers for $499 that far surpass the performance of the old ones.
By the same token, you can get a wider bandwidth, more linear, more transparent system today that will run circles around most systems from the '70s (including musical satisfaction) for far less (adjusted for inflation).
