I feel you’re discarding the free education and Healthcare system you were able to enjoy (because it’s available for everyone) until you’ve decided you could do better for yourself by yourself.
As a single straight healthy educated white dude, yes you could probably do better for yourself in the US, it just takes forsaking the meaning of solidarity. As long you don’t do the usual thing of coming back to Europe whenever you’re sick / having children because “it’s just so expensive in the US and it’s harder to have a family life there”
