Do you have ANY evidence to support what this meme is claiming?
What socialist country?
When was the socialist photo taken?
Sure, the problem with memes is that they don't allow you to convey specifics, but instead, just concepts, no matter how inaccurate they are.
But here on the flip, they've anticipated that shortcoming. You have the headline, where you posted the silly and preposterous OPINION that "Capitalism is Unsustainable", where you could have put a link to a story supporting your OPINION.
Or, you have as many comments as you'd like to post, to help support your OPINION.
But you chose not to, so that pretty much shows how much confidence you have in your OPINION about a system being unsustainable that has been functioning for approximately 400 YEARS.
