Look into government waste. If one thing is certain, government is NEVER efficient.
SS only comes from FICA- the government doesn't contribute when a pension plan replaces it and public employees can be members of AFSCME (American Federation of State, County and Municipal Employees) or other public retirement system, as the link shows. Employees pay their 7.65%, employers pay the other half and many pay the 'self employment tax", at 15.3%. During severe economic times, the employees may see reduced payment (2008-2009) and IIRC during COVID). I don't think employers saw a reduction on their side, though.
High earners making up to $176,100 and nothing above that for FICA.
Understand when employers pay the standard 7.65% FICA tax, the exceptions that apply, and how self-employment affects tax responsibilities.
