Fulfillment is a hard thing to quantify. Maybe unemployed people feel bad because they aren't doing anything, or maybe they feel bad because there is nothing for an unemployed person to do when everyone is working. Maybe they feel bad because other people make them feel bad for being unemployed, through their pity or indifference or even well meaning attempts to help.

You are completely right that it sucks to not have a job, but its possible that's a reflection of how social life is structured and not some biological Protestant work ethic. Right now "I work at X company" is shorthand for "I am a a productive member of society". That certainly benefits companies and certain types of people. But it's not the only imaginable value system. And I suspect that people who feel valuable are a lot less likely to find solace in bottle of pills.
