It's worse than you think.
Why worry about SS or Medicare if Democracy is dead. Trump and his complicit Republicans will do anything they want and guess what .... the Democrats can not stop it from happening .... Republican controlled Congress will not stop it from happening .... the federal courts will not stop it from happening .... and finally the SC has already thrown in with Trump .... he is gold. O you think because a few courts have temporarily stopped Trump from doing crazy stuff, you're safe? I think Bannon already knows and soon the other right-wing gangsters will figure it out .... the courts have no enforcement mechanism. Trump can do anything he wants ...
So back to your original concern .... Trump is a de facto king.
