"Well the gist of it still holds true."
The gist of it - three years ago - was that in the main, young people tend to favour socialism and older people don't and I think that certainly holds true. There's nothing remarkable in it, most young people go through what might be described as a 'brave new world' phase. Lots of them will vote for socialism because politically they are clean slates - it's why Jeremy Corbyn made such an effort to promise the earth to first-time voters at the last election.
He'll do the same thing, next time around.
There's nothing wrong with being idealistic, almost all of us are like it at some point, the world needs idealism as well as realism. It all balances out in the end.
