The indispensable condition for a tolerable situation of the worker is,
therefore, the fastest possible growth of productive capital.

But what is the growth of productive capital? Growth of the power of
accumulated labour over living labour. Growth of the domination of the bourgeoisie over the working class. If wage labour produces the wealth of others
that rules over it, the power that is hostile to it, capital, then the means of
employment, that is, the means of subsistence, flow back to it from this hostile
power, on condition that it makes itself afresh into a part of capital, into the
lever which hurls capital anew into an accelerated movement of growth.

To say that the interests of capital and those of the workers are one and
the same is only to say that capital and wage labour are two sides of one and
the same relation. The one conditions the other, just as usurer and squanderer
condition each other.
