All over the globe, austerity sucks. From streets all over Europe, headlines are reading: "Austerity Sucks!"
Practically nobody (in the short term) benefits from austerity. Politicians don't, cuz constituants hate them for it, voting them out. Old people don't, for sure, cuz they want to spend now and push the invoice into the future when they're dead or nearly so. Businesses don't, particularly those who depend on government contracts. Perhaps bond-holders do benefit from austerity, at least to the degree their bonds continue paying and maturing and all is well in ratings land... pension plans hold lots of bonds, 401k plans, banks hold them, and governments hold them too.
If austerity IS implemented tho, the biggest beneficiaries will be the infants and little kids living today -- damn, it's too bad they can't vote! When they grow up, they will not live their lives as OUR debt slaves, if we cut spending now. The younger you are, the more you stand to benefit, regardless of your class. So, care about kids' future much?
Raising the SS age does impact everyone in the same way, however you can't implement anything that doesn't produce different effects in individuals. But that distinction isn't a reason not to implement something. We have endless examples. Taxes, food, rain, cold, heat, laws, etc... almost any condition will *produce* a different effect for each individual, even when each condition is equally applied and distributed. This truth has always been so and will evermore be so. amen. :)
