The last irony of a past life between the most uncomfortable counterculture and the rationality of the ends of the capitalist world, that is, Wall Street, was to die run over: Jerry Rubin literally crossed where he shouldn't have been, and he has been dead for many years but Happily, he has left an indispensable inheritance for rich and poor, blessed and marginal alike: DO IT! it is still a necessary book in a world where the revolution remains as a mischief, a clown or, in the worst and most common case, a crime; that is, a world in which the liberal trap par excellence (understood the liberal word in the other sense, which is not the American and positive used in the book), is to invoke the crimes of the left seated in power to justify other forms of the exploitation of man by man who have run with better luck. Basically, Jerry Rubin never stopped doing what he should not, even when he left the radical militancy and tried to subvert the system from the inside, but that is another story, and is told at the end of the Spanish edition of DO IT!
