This is such a pure expression of the economistic credo, it deserves to be framed and then prominently displayed in the home of every communist. The obvious inference is that communists should not take the lead in overthrowing the constitutional monarchy. It is no business of the workers how they are ruled. If you just hate 'the bosses', that is enough. And the more you hate 'the bosses', the more revolutionary you are.
Communists have a fundamentally different approach.
In countries like the USA, Germany, Australia, etc, our revolutionary democratic demands would be different. In such countries the immediate slogan ought to be 'For a centralised republic'. As for the UK, the monarchy provides modern British capitalism with its constitutional mainstay. Hereditary privilege is the very antithesis of democracy. Communists think we should exploit this for everything it is worth.
