Retirement Is a New Concept
Retirement as we know it is a relatively recent invention. For most of human history people worked until they physically could not anymore.
When Social Security was signed into law in 1935 the average life expectancy for men was 59.9 years and for women 63.9 years. Full benefits did not kick in until age 65. The retirement age was set above the average life expectancy. The program was designed for a world where most people would not collect for very long.
Today life expectancy is around 79 years and many people are living well into their 80s and even 90s. That is a very different world from when Social Security was invented and it was never designed for the world we are now in.
The Math of a Long Retirement
Let's say you retire at 63. You could easily live another 30 years. In some cases 35 or even 40. That means you might spend more years in retirement than you spent working.
"A portfolio parked entirely in bonds and cash is not going to survive 35 years of inflation, rising healthcare costs, and the general increase in the cost of living."
Social Security's full retirement age of 65 was set above the average life expectancy of the era. Today a healthy retiree may need their money to last 30 years or more past that same age.
The purchasing power of that money will erode year after year until what felt like a comfortable nest egg at 63 feels very different at 83. Inflation does not stop because you retired. Healthcare costs certainly do not. Property taxes do not.
