Money can travel in time – this is mainly thanks to interest rate. It is key to realize that you always borrow from your own future (both at a level of Government, company and an individual). All thinkers of old have warned us against the use of interest; we have made it a cornerstone of capitalist economy.
We are riding on a very curious, strong and untamed force – all our sophisticated mathematical models will never master the strength of money-time travel, we will never be able to anticipate future. No wonder this force kicks around and creates havoc from time to time.
