> Prices should get cheaper.
Does that include the price of labour? Are you okay with your salary going down? Because the historical record shows that's what happens during deflationary periods: producers of good/services see the price that they can sell things for goes down, and so they insist on their suppliers and inputs—including labour input—reduce their prices as well.
Why would it go down? The person is becoming more productive? Do employees at Apple salaries go down because the iPhone they're working on is worth less every year?
Again, tie it to things that decrease in price over time.
