How does Of mice and men show the american dream through the setting?

I think the book looks at the American dream as largely being an illusion both economically and socially for the masses. We see this in books like the Great Gatsby and of course most of Steinbeck. All of the men in the book have nothing but a futile hope for belonging and a place to call their home. The era and the system will not allow the marginalized to have a chance at whatever the American Dream is perceived to be.
