Yes all governments claim to do this but far too many are corrupted now by corporate lobbyists and other parasites who pay the politicians to do their bidding, protect their cartels and monopolies and ultimately end up with a crippled and inefficient un-competitive economy that results in spiraling debt and reducing living standards.

The proof of Chinas ongoing economic success is in its continuous and growing trade surpluses and increasingly in its strategic domination across multiple supply chains. China has won the trade war and has put the US military industrial banking complex to shame as US empire slips away and the west loses its centuries long global domination and wealth.

As I pointed out earlier you appear incapable of understanding the crucial dynamic synergy between a well operated government that supports and strengthens its strategic supply chains, infrastructure and productivity of its businesses in a mixed economy and a corrupt and crony capitalist neoliberal infiltrated one like USA where private capital owns government and creates endless wasteful cartels and rentseeking parasitic dynamics.

USA is losing its power and wealth because it failed to invest in rare earths and other strategic supply chains. Free markets do not solve all economic and political problems.

Quality of government is and always has been a significant factor in the wealth of nations.
