In the academic setting, you take (typically) lonely, interesting middle-aged men and beautiful, intelligent young women, and everybody's motivations for display and conquest are engaged to the max. Sublimated, this can be a powerful force for the good - Plato had a lot to say about that - but acted upon it can bring evils without end.

You can find many philosophy papers on the themes of 'love' and 'friendship,' most of which are cheerful and somewhat anodyne; you don't find many on the loss of friends, relatives, and lovers from death or alienation, though it happens all the time.

In Western Europe and North America some things are better than they were - at least relative to their moral nadirs - such as labour legislation, the opening of the professions to women, intolerance for domestic violence, but so much is still morally unacceptable - the weapons trade, cruel and unusual punishment, economic parasitism.

Even if you just want to make a simple clothing item for yourself or go for a long hike in the forest - something we imagine requires absolutely no resources - you have to go to the store and buy a lot of stuff, and probably use a car.

Epicurus thought that friendship and conviviality, which require present attention rather than being in an alcoholic stupor, as well as trying to understand and explain things, were the greatest sources of satisfaction in life, so there go most drugs.

If you live in an acquisitive society you are likely to be acquisitive, but it isn't deeply rooted in human nature, except in the sense that it's deeply rooted to be psychologically receptive to your peers and to advertising.

People's wants are not fixed; they generally want what others in their chosen comparison class appear to be enjoying and what advertising presents to them as attainable for them and as bringing happiness.
