I strongly suspect it's a variant on capitalism that:
1. Recognises that some industries (utilities, healthcare, etc) are not well suited to market provision and are state funded. i.e. the sort social provisions that many of the nordic countries have.
2. Recognises that extreme wealth inequalities invalidate the key principle that capitalist economics is premised on (that the market value of a good or service closely approximates it's societal value) and therefore imposes much stronger progressive taxes on very high earners to effective cap how much wealth a single individual can control.
> early stage capitalism (lack of regulation and all)
High tax rates (90% in some cases) and all
See South Africa for an example. Power production is slowly opening up to market forces as an alleviation to the extreme mismanagement and corruption of the last 2-3 decades.
On the other hand, there are also some alternatives, like "devolution" of state services to the provincial or municipal level. The local Cape Town government is busy trying to gain control over the city's train lines from the government org that owns them, to provide better service.
