Unless you have a Scrooge Mcduck style moneypit, i don't think traveling the world is a viable option for most people, especially for younger people, who haven't had many years of adult life to truly have a huge income. It's most likely a stupid unintelligent insult from some other young dude who hasn't probably been that far in his life anyway. Evident for the fact he had time to cause an argument on the internet in the first place.
However I did hear about a guy who traveled for four years visiting every single country without using a plane, living on a hundred dollars a week, so it's possible if you know where about's you are going, and you spend years of planning out ahead.
Though in England, it feels like we don't even have to leave our own country to experience different cultures. We have many immigrants from India, Spain, China, Thailand, Pakistan, and Poland (amongst other countries) that come over here. So you do get a nice balance, and you are not culturally isolated like you are in America, which can be a problem as it promotes stereotyping, racism, and xenophobia.
