If gold were currency, since the supply increases slowly (mining) there would be a deflationary trend. As the productivity of society goes up, and the quantity of gold remains roughly the same, then each unit of gold will be worth more goods and services over time.
Question: what impact will this have on products such as some electronics that use gold? as the value of gold goes up relative to all goods and services, it would make such products more expensive. should that even be considered a problem?
