Who guarantees that willingness to work shall suffice to obtain work,
that uprightness, industry, thrift, and the rest of the virtues recommended by
the bourgeoisie, are really his road to happiness? No one. He knows that he has
something today and that it does not depend upon himself whether he shall have
something tomorrow. He knows that every breeze that blows, every whim of his
employer, every bad turn of trade may hurl him back into the fierce whirlpool
from which he has temporarily saved himself […] He knows that, though he may
have the means of living today, it is very uncertain whether he shall tomorrow.
