Just because the world could be worse, does that excuse us for not trying to make it better?

Shouldn't everyone be working to further the revolutionary effort /end concepts such as tyranny, privilege, and wage labour?

Why should we give up now just because we have Iphones and flat screen TVs, what about liberty, equality and fraternity?

No, we should not give up, but don't expect that with Trump. He doesn't even know what he's doing half the time, and discourse is his main objective. It's always been his game.
Our only hope is that he not do too much irreversible damage before Democrats get back into the White House. And try to repair the damage Trump does.

Some people actually do strive for improvement- many people.

Why should everyone be doing what you believe they should be doing?
