The Democrat plan will eventually only target responsible Senior Citizens. It will reduce benefits for those who have EARNED their entitlements, especially if they have acted responsibly and have other income, but make sure those who act irresponsibly are not harmed.
It targets their most hated sector most, retired Military (and Civil Servants) since the cut in EARNED benefits will include not only Social Security but their pensions. In the case of Civil Servants, the pension was funded by AFTER TAX contributions and in both cases (Civil Service and Military) was presented as a BENEFIT for recruitment and retention.
In legal terms, it was a bargained for consideration, but the employer has decided to steal the money.
