The video clip was amusing, because it went to great pains to demonstrate the foolishness of our obsession with materialistic distractions - at least as Epicurus would have seen it - and then goes on to talk about how Epicurus was eventually obsessed with financial independence and the ability to make a break with society and all of the negative and restraining aspects inherent with it.  The irony is that the video clip talks about how we can't buy our way to happiness, and yet this is exactly what Epicurus tried to do.  The type of purchase was different, but it was a purchase all the same that he saw as necessary for a pleasurable life.    

The narrator of the video opts not to comment on Epicurus' thoughts on friendship.  I'd say it's safe to say that many Americans are discovering how important friendship is, as we find themselves more and more lacking in that department.  And I think there is much to be said for the idea that friendship of a closer and more accessible nature can be a powerful promotion of happiness in people's lives.  However, having experimented with communal living, I can assure you that Epicurus probably found that this was not as simple as it sounds.  

Having known a fair number of people - and having been one myself - I can pretty well vouch that internal means to happiness - Epicurean or otherwise - seem to be pretty much universal failures.  I don't think this is a coincidence.
