alot of retirees are still working. even some that retired around 55-60s. it just not enough income on RETIREMENT alone, unless you are RICH or well off, i had some "retired" uncle/aunts in thier 50s-60s that are doing stocks/investments instead carefully.
with the off chance if you someone that is spending beyond thier means, and one other person is the sole breadwinner(like parents, one is overspending and hoarding and the other is apushover , it wont be enough.
keeping the russia and the MIDDLE east economy afloat, because the politicians pockets are in too deep with these 2 countries
