There are those that may never need Entitlements as they grow older, but, that doesn't mean the entitlements should not exist.
I believe 'means testing' is vital to the best outcome of our nation and the need for any individual to receive entitlements.
Disability can take away every dime of wealth. When our young people see investment to their best outcomes as opposed to entitlements they are also ignoring worst case scenarios that will place them in very bad outcomes.
When the global economic collapse of 2008 hit, I can only imagine the panic that struck those unable to work, but, deeply invested for their daily needs and quality of life. For the USA to consider complete dissolution of Entitlements is grossly negligent of government.
Until it is obvious the Entitlements are stable for more than two generations, I don't see why there should be any change in them EXCEPT for means testing.
Means Testing will remove some of the burden of 'future need' and will begin to provide a realistic picture of the needs of low income earners whom have contributed to this great country, but, will never have the method to secure their sunset years in a real way.
Unions have to do their part and be partners with the USA to encourage benevolent and intact retirement plans AND safe work places where disability is a word of the past.
