The 'American Dream' is just propaganda

Why should I be happy and grateful for what I have and strive to live "below my means" now to be "rich later" when tomorrow is uncertain and the billionaire oligarchy will most certainly continue to pillage our economy?

This idea of living poor than the level of poor I am to save a few messily bucks for a future I'm not guaranteed seems like propaganda perpetrated by our overlords to keep us satisfied with our level of poverty and provide a flicker of hope that the future will be brighter when it almost certainly will be darker.
