Here are some other things that provided lot's of jobs for people.
-The slave trade
-The Nuclear weapons industry
-The Khymer Rouge
Just because something provides employment does not mean that it is absolved from all sins. Nowadays anything can be done if it provides jobs, this is why we can't end fox-hunting, nuclear power etc because when the jobs argument comes up it seems to overshadow all other issues.
The vast majority of all jobs are useless and only exist for the sake of jobs. The world could exist with only a few people working (let the "workaholics" do this), but this would fuck up the economy and we can't have that can we?!
We are constantly hearing about the problems facing us in providing homes for the increasing world population. We don't seem to realise that they will also have to work somewhere. This will result in more factorys, more pollution, more greenery destroyed, more useless products that have to be made out of the earth diminishing resources, more bureaucracy, and more fucking office space.
Let's rethink work, only do what needs to be done, leave the world alone to heal and let's all have a bit of fun instead of dreary, boring, mindless, repetitive, useless fucking jobs.
Full enjoyment not full employment.
