If the retirement age for SS benefits is increased to about 70 years of age, it would affect only those individuals presently in their 50s.
The older a person is prior to getting SS, the more likley the person will be dead prior to the initial payment of benefits or the number of years that person actually receives SS benefits.
For folks in poor health 65 or younger is a good bet. For folks needing money immediately, it is also a good bet.
In general, I think that increasing the SS age is not a good and fair idea, especiall when you consider how many Americans earn a living, today. by perfomr hard labor.
At the pig processing plants in Iowa ( for example), do you think that any man or woman who labors in the " killing pits" in temps at or above 110F will be able to endure 40 years of labor, before the age of 65+ and the receipt of SS benefits?
