The state, as like a concept, doesn't 'inherently' want anything, because there's infinite ways to form a state. The organization of human being in which every person has a voice or say, does tend to operate in a certain way.
The main difference between the public sector and the private sector is that the public sector is somewhat of a democracy, and the private sector is much closer to a monarchy. Obviously our democracy is not perfect, but it's a lot better than "the dictator (board and CEO) makes the decisions, you are cog, please comply".
There's market forces to mitigate that, just like we can say there's foreign affairs to mitigate dictatorships in nations, but that doesn't work if you have a lot of power. Exhibit A: Russia. Russia was supposed to be discouraged from invading the Ukraine, but ultimately, there's nothing stopping the King from doing that.
Let's look at Tesla. Elon Musk is supposed to be discouraged from doing a Nazi Salute because free market, but ultimately there's nothing stopping the king from doing that.
For our government, it makes decisions with the coordination of thousands of people, many of them poor and will experience the direct consequences of those decisions. The further we stray away from that core principle, the worse it gets. Just in general, when we talk about human organization.
