No, governments are not states. States are states, and they are not elected.
In communism they're elected, or at least communally decided. That's the flaw with capitalism - political entities are democratically elected while economic entities (and wealthy people) arise as a course of "might makes right" in a slightly more complicated system.
Regardless, I gather from your statement that you are defining the state as not only the political component, but the entire entity, which includes the economic component.
It's not a matter, at the bottom of line, of whether a government is democratically-elected. It's not a matter of whether a regime possesses effective checks-and-balances. It's not even a matter of whether public officials are honest and hard-working. It's a matter of capitalism.
Capitalism is founded on the wage-relation. Workers must be disciplined, contained and exploited. This is an inherently predatory relationship, and not one that can be reformed away. Get rid of the landlords, the bankers, the pawn-brokers, whatever else you like, the wage-system remains. Nationalisation the whole thing, the wage-system remains. Declare a "planned economy", take everything into the state, abolish private privilege, the wage-system remains. Profits must be produced, or the whole system comes apart at the seams.
Predatory behaviour is built into the bones of our world. Even if you ignore all the bankers, the landlords, the bosses, money-lenders, pawn-brokers and poison-merchants, even if we imagine that they could in any non-fantastical world be done away with, the essentially violent, predatory core of the system remains.
That depends on what you define as "intent". You alluded to the notion of a state reasonably aspiring to prevent predatory behaviour. This "aspiration" has a notion of intent built into it that must be explored further in order to answer the question.
Suppose the following. A magical group called the "Illuminati" somehow control a lot of what happens in the world. They decide how states will function (through subtle influence or some other way). Back a long time ago, they moved humanity from an era of slavery to an era of feudalism. They did this either because a) they foolishly thought feudalism was the least predatory system that is possible OR b) they believed feudalism was the least predatory system human social development could muster at the time.
The Illuminati's state is less predatory than the previous. Now slaves, instead of being worked to death, are only mostly worked to death, and get to keep a pittance of their work instead of nothing. They also have slightly more options in choosing their masters than before. However, predation still exists in abundance. Is this is a state that attempts to prevent predatory behaviour? Bear in mind, it was established by the Illuminati for the sole purpose of preventing predatory behaviour (since the Illuminati are extremely incompetent).
Now suppose the following. Human social development has a direct influence on states and their functioning. At first we had slavery, and then eventually feudalism. The inequity brought upon the people by feudalism led to worker disgruntlement. In order to appease workers' demands for a non-predatory system, a king establishes the "free market". This is still predatory, but less so on the people than before. Is this new state aspiring to prevent predatory behaviour?
My Point
My point is that human social development lead to the evolution of states. I would venture to guess that your assertion is that each social system evolution came as a result of predators attempting to maximize predation under an adapting order, and perhaps
in spite of workers (and their demands for equity) instead of for them. Perhaps I am too much of an optimist and/or you too much of a pessimist, but I perceive a great attribution of such change to be separate from the people involved, with no intent (i.e. some mystical concept of social or cultural evolution, rather than a group of people).
I also believe that the advent of democracy has changed a multitude of factors as well. Currently, the wealthy will have a great level of influence, affecting many policies across the board. However, to an unprecedented extent, the people now have a not-insignificant level of influence as well. Capitalism can indeed be "reformed away" to be less predatory on the workers. At least until the people collect sufficient education, awareness, and power to truly change things.
What bearing does whether or not a given government is "democratically-elected" have on all that?
We would have to look at capitalism's shortfalls to address that. The way I see it, there are only two outcomes that fundamentally flaw capitalism.
One is that the residual fruits of workers' labours are remitted to the capitalists. I say residual since workers do get
some fruits of their labour (wages), but this point is meant to also encapsulate the illegitimacy of wealth. That is, that capitalists can earn economic benefits by merely owning wealth, rather than performing actions deserving of such benefits. An argument made for the idea that they had performed actions in the past leading to their wealth is flawed from both an inheritance perspective (where does this wealth go when they die?) and from the circular argument that presupposes that earnings made under such a system are indeed legitimate.
The second is that the capitalists have total economic control. Even if all workers were to be paid handsome wages, it would still be the wealth-owners who would make all the decisions and have all the control over how such wealth would be handled and distributed. Workers would still have to choose their "master" to provide wages necessary for living, while the masters control all aspects (to the extent they wish).
A democratically-elected government has a higher degree of influence from the workers themselves, and can align the system more to the workers' goals. The first flaw can be addressed through taxation schemes that "redistribute" the wealth to some minor degree. The second flaw can be addressed by providing the people more power, since they now indirectly control this political government that can influence the system and aspects thereof.
Just because political reform has been slow or ineffective in the past century doesn't mean that it will continue to be
just as slow. I would expect an exponential increase in effectiveness over time as technological advances increase education and social communication and commentary.
In Short
It's all getting better.
I hope.
