What is American dream?
Immigrants to America, especially during the industrial era, came from countries where regardless of their work and effort, they were still starving and poor. The idea of the American Dream is that you get to enjoy the fruits of your labor. That in America, anyone can own property, start a business, educate their children, etc. If you work hard and want it bad enough, you can rise higher and higher. Whether that means having all the things you mentioned, or just having a decent home and taking a vacation once in a while without having to file bankruptcy in the process.
