I disagree with your initial proposition on a number of grounds. Firstly, it is hard to argue whether society promotes having a job or doing hard work when in reality, society promotes both. For the vast majority of people, a "job" is the only thing that can sustain them with an income. Most people are not intelligent, experienced or creative enough to be entrepreneurs and that entails that they will likely be employed by someone else which is fine. Employers do give you a job but the language is less important then what that actually entails. You are free to stop working at any time if you really don't want to, that will likely have negative consequences for you but you are not forced into subservience.
I don't know why you argue that society promotes the idea that individuals can't succeed. America idolizes entrepreneurs more than any other country that I am aware of. Your argument would actually be more valid in a country like Japan but that is a different topic entirely.
I don't think small businesses are "failing so badly" . Large corporations like Walmart or Amazon replace smaller businesses because consumers like them better. That is all there is to it. Whether or not that effects quality is at best, subjective. Your argument really lacks substance. You aren't explaining why something is worse or even if it is true, you are just using negative language to reflect your world view.
What evidence do you have that corporate America promotes the idea of "the master and the slave"? I think is safer to say that they promote the idea of the consumer and producer. Corporations don't care what consumers outside of their business and that is a fair, voluntary relationship if there are ever was one.
I don't see much evidence either that we live in a society "dominated by large, impersonal entities". I would like to see what you mean by this in detail. I have absolutely no idea what you mean by capitalism or at least American capitalism making people "dependent". In what type of society are people not dependent on others? Tribalism? In any type of conceivable society, people are dependent on others in order to build a society and an economy. Whether or not that is voluntary or not it remains a fact and if anything, the fact that it is voluntary reduces dependency if anything.
I don't think our country is sick and our society is sick. I'm not a big fan of American culture but I would not have been a fan of it in general at any point in time. People in America carve out lives for themselves and generally do well. Poor Americans still have high standards of living and middle class Americans have a lot of freedom and choice in their lives. Work culture is arguably bad but what people do in America is highly diversified. It is one of the countries in the world where anyone from anywhere can make it big if they are intelligent and dedicated enough. There are not many other places where that is the case.
My problem with your argument is that it lacks an argument. You are just using adjectives to describe your own world view and I cannot relate to it because you don't ground what you are saying in facts. Even if America did promote "complacency, mediocrity and subservience" why would that necessarily make it a failing nation? I would argue Japan embodies those things far more than America does and many people would view Japan as a much greater nation.
What do you mean by "the people in power who want you to fail"? Business leaders? Politicians? I can't understand your vague, abstract arguments. I'm a teacher and I grade papers and arguments for a living and if I had asked my students what they thought about the contemporary United States and they presented me with what you just wrote, I would ask them to rewrite it with more specific, concrete examples. Your writing is like a politician, it is just empty rhetoric unless you can back it up with specifics.
