20. (1) Work is a right, a duty and a matter of honour for every citizen who is capable of working, and everyone shall be paid for his work on the basis of the principle “from each according to his abilities, to each according to his work”. (2) The State shall endeavour to create conditions in which, as a general principle, persons shall not be able to enjoy unearned incomes, and in which human labour in every form, intellectual and physical, shall become a fuller expression of creative endeavour and of the human personality.
