Sure, but 'jobs' are not everything, they are just one measure and if you look at what is listed under 'services' then you'll find that a lot of those services are actually in support of the other 27% of the jobs.

Labor and capital, what else is there?

I would just liket o say that I think that HN is very diverse. I come here to read tech and progress news. But this is also the best site for reading about culture, ethics and other issues that I can find. All newsmedia eg BBC, Guardian, PBS, ABC, New York Times etc., all have an editorial axe to grind. By listening and discussing here with the very people that make 'progress' and in a real sense shape culture I gain very much and am allowed to have an opinion. Most people here are awesome considerate people and the trolls don't usually stick around very long.

RE: 73% jobs - let the machines do the work so people have time to think - and to create culture - and to progress!! Yay HN, yay progress, yay culture!
