So, was ditzing around today and looking at stuff. Apparently full retirement age in our country is 67 for people born after 1960. This is still more or less the same age that was initially dictated when it was first enacted in the 60s. The eligibility age has risen by two years in the time since then. In comparison, our life expectancy has risen 9 years to an average of 75 years for men and roughly 80 for women. This seems rather out of place, as do many social programs that were enacted decades ago. For whatever reason, pretty much none of our legislation is ever tied to predictable increases. Even a simple algorithm that raised the age by half a year for every increased year of life expectancy, with a double increase for every five years of increased life expectancy. Even that's being incredibly generous. When the retirement law went into effect the average life expectancy for men was 66-67 and the retirement age was 65. However, I do feel like that's still pretty fair since life expectancy isn't the most accurate numbers to stick by because it also takes into effect people who die far earlier than the retirement age. A more accurate method, imo, would be to take the life expectancy of those who reach the retirement age ot something close to that age.
As an example, raising the retirement age to 70 would save some 120 billion dollars over the next decade. However, we also have to weigh the negatives of something such as this. In a struggling job market, this means positions would be filled longer than they already are. Creating more unemployment. Frankly I think that such a reform also needs to come with an educational, cultural, and systematic change. Currently many people view retirement benefits as a main stream of income when it shouldn't come out to anything more than a supplement. There isn't a culture of saving and investing in the main body of the populace and I feel that is due to a lack of general financial literacy as the result of a lack of education during primary schooling.
