While "sweat equity" is a fun ideal, in reality it is not very similar to passive equity. That is in essence what wealth in capitalism is. Income via passive equity.
When one is dependent on "their minds & muscles", what that actually means is that they are forced to work in government approved income activities(nothing illegal) or face imprisonment or death. That doesn't sound much like liberty to me. On the other hand, those with enough passive equity no longer need to work in government approved activities provided by the asset class, and very much do enjoy the benefits of liberty.
That said, it is very obvious to are tied to an ideology(likely because it benefits you a great deal personally), and I won't spend any more time trying to enlighten you.
