from The Communist Manifesto

. . . the theory of the Communists may be summed up in a single sentence: Abolition of private property.
. . .
You are horrified at our intending to do away with private property. But in your existing society, private property is already done away with for nine-tenths of the population; its existence for the few is solely due to its nonexistence in the hands of those nine-tenths.
. . .
It has been objected, that upon the abolition of private property all work will cease, and universal laziness will overtake us. According to this, bourgeois society ought long ago to have gone to the dogs through sheer idleness; for those of its members who work, acquire nothing, and those who acquire anything, do not work. . . .
