I don't know that real unemployment is lower.  2008 created a permanent underclass in this country.  I guess you can't say it created this class, but it greatly expanded it.   So many formerly middle class people joined this underclass because of their age.  If you were 45 or over, or at most, 50 or over, and lost your job in the crash, you were very unlikely to find another one.  Those people are totally fucked.
		
		
	 
I do agree that those 55 and over had a very hard time finding new jobs, especially at similar levels of pay.  This was due to the discrimination that occurs that we pretend doesn't occur.  Younger workers are cheaper and have greater potential longevity.
	
	
		
		
			We should have lowered the SS age, expanded Medicaid, dropped any cap on UI (btw, UI is totally stimulative and anyone against those benefits is not doing it out of fiscal concern but simply for ideological reasons, which basically comes down to spite), and instituted real jobs programs.  God knows this country is a shithole and could use a lot of work.  Our infrastructure is a mess.
		
		
	 
1) Lowering SS is a horrible idea, it would only further exacerbate the problems within SS.  We have the ability to take care of the current problems, but lowering the age would likely cause more problems than it solves.
2) Expanding Medicaid... I assume you mean by increasing the income eligibility level... which I would agree with in principle, but obviously the level of increase is up for debate.
3) Unemployment Insurance is not 'totally stimulative'... that money comes from corporations who pay unemployment insurance.  The longer the period, the higher the premiums will be for companies.  The higher the premiums, the more cautious companies will be to hire and the more they will look for automation, increases in current labor productivity etc...   Like anything, the money has to come from somewhere.  If you provide endless unemployment benefits, then there is less incentive to find a job.
4) Jobs programs are a very good investment in my opinion.  Welfare recipients should automatically be enrolled in job training programs to help them break the cycle of dependency on the government.  Obviously child care would be a necessary component to allow the adults with children not in school to participate.  Unemployment recipients should be provided the opportunity to learn a new trade/profession, especially if their previous job was in a dying industry or one that has become more automated/off shored.
5) Our country is hardly a shit hole.  
6) Infrastructure... a FAR FAR FAR FAR better use of money than simply extending unemployment benefits (couple this with the jobs training programs you mentioned... and away we go)
