The Visual Capitalist reports The Pension Time Bomb: $400 Trillion by 2050. The above image is a small section of a huge pension infographic.

According to an analysis by the World Economic Forum (WEF), there was a combined retirement savings gap in excess of $70 trillion in 2015, spread between eight major economies: Canada, Australia, Netherlands, Japan, India, China, the United Kingdom, and the United States.

The WEF says the deficit is growing by $28 billion every 24 hours – and if nothing is done to slow the growth rate, the deficit will reach $400 trillion by 2050, or about five times the size of the global economy today.

In the United States, it is expected that the Social Security trust fund will run out by 2034. At that point, there will only be enough revenue coming in to pay out approximately 77% of benefits.
