I agree with some of that. At its inception, capitalism was revolutionary and could have been described to be 'like an eagle'. It was revolutionary inasmuch as it brushed aside the moribund and restrictive influence of feudal absolutism, and embarked upon a scientific crusade of discovery. In this respect it was revolutionary. It became reactionary very soon afterwards, however, as the progress that was made in the fields of industrial and agricultural production were not used to improve the lot of everyone but merely to feather the nests of the privileged few who had the wealth to invest in the new enterprises. Workers created the profits but were/are denied access to the true value of their labour. Regarding the collapse of capitalism, of course, the system is very unstable and fraught with contradictions. If the system collapses, what do we replace it with? Of course, it's the historic task of the proletariat to create a new society...a society that is able to harness technology for the benefit of all people throughout the world. Unfortunately there is no guarantee that workers will step into the breach. When Rosa Luxemburg said that we face a choice between socialism or barbarism it could be interpreted in two ways. Firstly, we on the left view the defeat of the German Revolution and the subsequent victory of fascism as barbarism. At the same time we can also view her words as a dire warning of near total destruction of the technologies we've come to rely on, and a return to earlier forms of social organisation such as feudalism. Malcolm X developed an excellent analysis and critique of capitalism and my guess is that, over time, he would have moved over to the cause of socialism!
