First published as “Thoughts within the Coronising Siege” Political Animal Magazine, http://www.politicalanimalmagazine.com/themes/theory/, also utopian-studies-europe.org/coronising; A series of fragments from e-mail debates with comrades during the corona lockdown in March ‘20 and a bit after. Sections: A/ long duration prospects, centrally a further mutation of predatory capitalism; B/ short duration: the rulers’ the toggle between disease control and their profits leads to millions of unnecessary deaths, the need collective self-defense (organising) arises. In Europe, the political and financial bureaucracies centrally safeguard business activities; the timid strengthening of State capacities or palliative measures – limited exemptions from the payment of housing, small sums for the poorest – do not sufficiently guarantee the labour and health of the working people, now or in the future. C/ This changes all: possibly hundreds of millions infected are on the horizon if India and the rest of S. Asia, Africa, and Latin America (and Russia?) are counted. Planning for the working people and its welfare, spurned as communist, must be introduced: the choice is to organise or be ground down into a new slavery plus eco-catastrophe. Global capitalism is not biologically sustainable for the species Homo sapiens.
