Democracy itself doesn't make society good, or protect it from evil. It can be majority tyranny. And modern democracy is easily made to work for the benefit of elite, not for the people.
I'm not clear what you mean by "modern democracy."
Democracy, at least, provides a bulwark against exploitation.
For example, the US today is not a democracy, as the Princeton study illustrates. Government has been captured by Corporate interests.
Economic hierarchy seems to be in all human societies, even in communistic. I think it is not equal when some people have to work for other people as in socialistic systems they have to work. I think it is slavery.
Name some communistic human societies.
I think you're misrepresenting communism.
In socialist systems people do not work for other people. That's capitalism.
Are the communist Hutterites slaves?
In socialism people work co-operatively, make business decisions co-operatively, and share any wealth generated co-operatively. The means of production is owned co-operatively, so cannot benefit any single group or individual. Socialism is economic democracy.
But the "socialists" that so disturb the capitalists are not even advocating advocating pure socialism. We happy with a mixed economy, with a socialized commons, and capitalist businesses.
I think governments job should be to quarantine human rights and freedom. This means, all people should have possibility to found own job, factory and own own means of production. Obviously, they also should have freedom to choose to work for someone else, if they want. In all cases there is some owner, person who decides how the means are used. I think the best would be that people are free to own and work as they want.
All well and good, but government's job should also be to curb the abuses and exploitation free trade is prone to. Left unchecked, businesses eat each other, monopolize, and you get the wealth trickling up to the oligarchs, a shrinking middle class and stagnant wages.
Government should be
We the People. It should be "of, for, and by" The People. Dedicated to the prosperity of The People. It should protect the interests of The People from the exploitation of the "Economic Royalists."
I think minimizing the costs of production and maximizing profits is the benefit of everyone who works, if he is paid fairly for that. And I think it would be good to have that goal. I think goal should be that people work only that much as what is necessary.
The workers
are a cost of production, so is workplace safety, toxic waste disposal, product safety, &c. This is a recipe for low pay and stagnant wages; for market consolidation and oligarchy
I think governments job is to ensure that people are free. If workers have only one option, the government is the problem.
Free in what way?
Isn't it also The People's (government's) job to manage the commons, ensure access to utilities, police protection, fire protection, Safe food, water and pharmaceuticals; education, healthcare, clean air and water? Isn't it government's job to guard against exploitation, ensure fair wages, workplace safety, prevent monopoly, regulate banks, and, basically,
"promote the general welfare?"
If all generate wealth, there is no need to share, because all generate wealth. But, "You see, in this world, there are two kinds of people, my friend: those with loaded guns and those who dig...." - Clint Eastwood. In practice, in socialism, there is two kinds of people, those who work, and those who benefit from the workers. This means, there is government, that steals what people earn and then share some leftovers of what they collected.
It's not just generating wealth, it's who the wealth goes to. In Capitalism, most of the wealth goes to the owner class, and, as you said, the owners seek to minimize the cost of production, ie: wages, workplace safety, pollution regulations, &c.
If you think socialism is something else, I don't think it exists in this world.
It exists mostly in small groups and companies, with a few larger corporations like Mondragon.
But, as I said, what we're advocating isn't pure socialism, it's socialization of natural monopolies and the commons, and private ownership of non-essential enterprises
