Ral Dalio, the billionaire Bridgewater hedge-fund star, narrates an animated video posted on YouTube Sunday, in which he delivers his “simple but practical” take on how the economy works. He sums up his half-hour presentation with three critical rules of thumb that have served him well:
Don’t have debt rise faster than income.
Don’t have income rise faster than productivity.
Do all that you can to raise your productivity.
