Hi cosinenonqua,
This seems to do what you are asking, but you might not want this sort 
of plot:

plot(cosinenonqua$American.Workers,col=2,xaxt="n",ylim=c(0,55))
points(cosinenonqua$Foreign.Workers,col=4)
axis(1,at=1:3,labels=cosinenonqua$Occupation)
legend(1.7,30,c("American","Foreign"),col=c(2,4),pch=1)
