I've known farmers at both ends of the scale (i.e. the ones who live hand to mouth and one bad harvest is a tragedy vs. the ones who moan about things yet can fork out £400k on a new toy come harvest time).
It's a bit like contractors - I've met ones who charge the earth for doing bugger-all and those who work all the hours possible for pitiful day rate.
IMO generalisations are only permissable if they are funny :P
