Corruption in achieving your ideal system. How do you prevent it?
The prevailing political culture / revolution / paradigm would predominate in terms of what the overall societal *ethos* is -- against corruption, against opportunism, against privateering, all the way to abolishing private property itself, to *collectivize* all productive means, particularly the means of mass industrial production.
'Corruption' in a *revolutionary* political-culture context would basically mean 'backsliding', or 'counterrevolution', for *private* (not collective) interests.
I can't *guarantee* that the prevailing political culture will be 'anti-corruption', or 'anti-profiteering' (as during the pandemic), or full-blown 'anti-private-property'.
So I myself *can't* prevent it -- that's about the overall 'struggle', or political ethos, that almost allows a coup in the Capitol building, or military rule in Myanmar, or a coup in Haiti, or wage-slavery globally.
Suffice it to say that prevailing political sentiment / ethos would have to solidly be for *workers power*, and for *workers collectivization*, to battle and mitigate 'corruption' in such a political environment.
