[I]t is our interest and our task to make the revolution permanent until all the more or less propertied classes have been driven from their ruling positions, until the proletariat has conquered state power and until the association of the proletarians has progressed sufficiently far – not only in one country but in all the leading countries of the world – that competition between the proletarians of these countries ceases and at least the decisive forces of production are concentrated in the hands of the workers. Our concern cannot simply be to modify private property, but to abolish it, not to hush up class antagonisms but to abolish classes, not to improve the existing society but to found a new one.
