From each according to their ability, to each according to their need. - Karl Marx

All fixed, fast-frozen relations, with their train of ancient and venerable prejudices and opinions, are swept away, all new-formed ones become antiquated before they can ossify. All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses his real conditions of life, and his relations with his kind.

Just as man is governed, in religion, by the products of his own brain, so, in capitalist production, he is governed by the products of his own hand.

Pengabstrakan kerja dalam bentuk uang mengandaikan dialektika di antara perkerjaan/kerja yang secara sosial dibutuhkan untuk membuat barang dagangan/komoditi/jasa, dengan proses produksi kapitalisme yang justru meniadakan kerja manusia itu sendiri. Sehingga proses produksi kapitalisme dalam kelanjutannya hanya menempatkan manusia sebagai bagian dari proses akumulasi modal.
