I cannot remember when I first heard or read the phrase "American Dream", but will admit that I have not researched its origin.
It turns out Wikipedia has a good entry right here:

North of us, do people talk about the "Canadian Dream"? It may not be called as such, but let me tell you that something like that is still alive from what I saw.
I have always wanted to travel to the Okanagan Valley region of Canada, and had a chance to do so when coming back to the US from Alaska in my RV trek earlier this summer. South of Kelowna, along Highway 97 all the way to the US border is a land of fruit orchards and wineries which is possible with water from the Okanagan River which flows south into the US.
My wife loves fruit orchards, and I managed to find convenient spots to stop at three different orchards for her to get out and to visit. All three had a fruit stand, manned by an Indian. And they looked like the owner or family member, meaning not hired help. Looking around, we saw that the farmhands were also South Asian.
At one of the fruit stands, a nice elderly man identified himself as the owner of the orchard. He was definitely a first-generation Canadian. We asked what fruit he grew, and he said only cherry, but he was in the process of buying an adjacent lot with different fruits.
I found it fascinating that South Asian newcomers were prevalent in this fruit growing region. Were they successful because they did not mind hard work, and took over orchards that original owners had problems passing on to their heirs to operate?
I later researched, and found that in the town of Oliver, Sikhs own 70% of orchards and wineries, which they bought from the Portuguese immigrants who migrated there in 1950s. Hard work pays off for these Sikhs, and I am happy for them.
