Jeff thank you for all you have done showing me that prices decline for ever. Have you seen the film “What is The Problem”?. And how can we measure the global productivity increase and productivity increase of sectors of the economy, and of businesses in a world where the price is skewed? Productivity is often measured as real gross domestic product (gdp). Per capita, per year increase. But to get to that “real” gdp we divide the nominal value (in dollars) by the price. The price is skewed. CPI. That doesn’t measure anything. Should we divide everything by the “price” of Bitcoin? Gold? Oil?
