"Marx" has too much baggage at this point to insist on him as any kind of central point. We should take the serious contributions he had to make and move on. In fact, no ideology as such is needed, simply eclecticism and practicality.
Marx explained why the capitalist system of production could not deliver on the promise of emancipation.
He showed that it would become a hindrance to our development and that it would become necessary to move on to a more useful system, for practical reasons.
The eclecticism and practicality born out of the capitalist system of production is exactly what has led us to this moment in time. It has delivered to us, President Trump.
And keep in mind also, the baggage associated with Marx was also born out of practicality. The ruling capitalist class wants Marx forgotten, for practical reasons.
..... In that case we do not confront the world in a doctrinaire way with a new principle: Here is the truth, kneel down before it! We develop new principles for the world out of the world’s own principles. We do not say to the world: Cease your struggles, they are foolish; we will give you the true slogan of struggle. We merely show the world what it is really fighting for, and consciousness is something that it
has to acquire, even if it does not want to.
The reform of consciousness consists
only in making the world aware of its own consciousness, in awakening it out of its dream about itself, in
explaining to it the meaning of its own actions.
