Conservatives put their faith in mechanization, automation, computerization and robotics to eliminate such jobs completely ~ starting with middle-management!
If output can be achieved with fewer people, the people whose jobs are eliminated can (must) find something else to do to create value. When this is done, we are ALL much richer (same number of people working - more goods and services to go around.) Mechanization, automation, computerization and robits is why we don't all work the fields all day to provide ourselves enough food to stay alive. A few people can provide food while others perform a million different functions to serve their fellow man.
It not then you have robbed all those people of jobs.
Of course, that would mean that not many people would have mugs. And probably there would be no coffee. And there would be no Internet. No computers. No electricity. No cars. No steel plows.
In fact, we will have to get rid of plows all together since with them one man and a team of horses can do the work of ten men and so he is depriving those nine men of jobs.
Wagons will have to go too. They can carry more then one man can and so you are putting bearers out of work.
So I guess we will go back to living in huts, digging little holes with pointed sticks to plant seeds and grind our grain on two flat rocks BUT EVERBODY WILL HAVE A JOB.
Sounds like paradise doesn't it?
