A thought: the "public-private" tendering model where governments put out contracts for specific tasks makes certain types of public infrastructure impossible to have in a way that is often missed even in critical analysis of capitalist models, because it eliminates the kind of high-investment infrastructure that can only come to exist from a government-scale entity saying "we need to have this thing and we do not care how much it costs", something that is fundamentally impossible for the incentives in a tender process to support.
