The central banks are turning off the money taps, growth is pretty stagnant across all major economies (bar the US and UK). Wealth inequality is rising while automation is arriving with a bang putting people out of their jobs and at an increasing rate and also putting downward pressure on prices as manufacturing costs fall, meaning the masses won't be spending much. China was a major driver of global economic growth but is undergoing a huge correction, Brazil has been in a recession since last year, Russia is suffering under sanctions, the Eurozone is becoming Japan mark 2, the price of oil is dropping like never before affecting the Middle East's ability to grow (notwithstanding the war currently ravaging the area). This all points to a period deflation.
Only people with money can make money with economic foresights.
