Fichte is a necessary step to both Hegel and Marx.

Freedom is a permanent problem for us, both unavoidable and insoluble.

It is rational to choose the right means to your ends to develop very elegant abstract formal theories of rational choice, and then turn these into what look like moral theories. Philosophers tend to be ravished by the formal beauty of such theories, and they don't pay much attention to the fact that our human limitations make them pretty useless in practice, while the simple point about instrumental reasoning is too shallow to be of much real moral interest.

We can make mistakes about what we ought to do, and these are not the same as making bad decisions about what to do.

It is both theoretically mistaken and morally wrong to regard others as objects of investigation rather than partners in free rational communication.

It would be nice, wouldn't it? if we could get comfortable about the problem of freedom. Kant thinks that we can't.

Capitalism has proven to be a far more terrible system than Marx could ever bring himself to imagine. Those who are so deluded as to find something good in it, or even feel loyalty toward it, are its most pitiful victims.
