In America you have to understand their history to understand their culture. 1776 and the constitution is deeply embedded into the psyche of Americans, manifests in many different ways. America took it upon itself to be independent and free of their current government, which you can see manifested today as a culture that expects no help from the government in terms of personal success, it is deeply stigmatised to accept support from the government, ,and people are really expected to 'pull themselves up by their bootstraps'. It creates a huge desire for social mobility, in Australia or the UK, being working class can be something to be proud of, working with one's hands and earning a honest life, not so much in America, one is expected to always want more and to show it off with flashy possessions. Rather than band together and create an environment that benefits the most people, Americans have setted on 'I've got mine, you get yours' based on the merit of individual success. A person is defined by their earning power, not their virtue or actions, and I fear this is becoming deeply prevalent in other countries due to American mass media exportation.
There is also a bizarre double think that many fall prey, the obsess over the ideal of 'don't tread on me' for fear of a tyrannical government but many will bootlick the administration that panders to their desires the most. The both distrust the government, but idealise a government institution like the military despite the fact that'd be the hammer of the tyrannical government they fear. I really feel this is a nation of double standards, 'I love Jesus but hate Islam', 'Help the poor, but don't tax me', 'You can't tell me what to do, but arrest that person for breaking the law', 'It doesn't apply to me, but it applies to you'.
Americans have great capacity for love and compassion but also an inherent greed and desire for more, money, clothes, food, sugar, coffee, drugs, entertainment, music, medicine, it drives them forward to innovate but in a very 'monoculture' way (how can I milk the cow for all it's worth?, do I abuse the soil to maximise my crop yield?). The short term over the long term, ,always looking for the quick buck. They cannot see the forest for the trees for what is good for America, only themselves.
