“It’s a wonderful life” is an American classic, that actually has a pro socialist message, what other popular movies exist that have themes, that most ignore?

I find the irony of this pro socialist movie is an American classic, while most ignore it showing the goodness of socialism(George Bailey gives up his own passions and dreams to devout his life to the betterment of society) and the evilness of capitalism(potter obviously represents the greedy nature of big business who cares nothing for his common man, but only what makes him richer)
