A chap like Jeremy would have had his eye to business had he had the chance. Don't forget,he liked money and nothing would have given him greater pleasure than to see it rolling in as opposed to rolling out again.
He'd have aimed for a millionaire status at the farm,a far easier position and prospect to have worked to back then than now. His father probably put him in the picture when he was discussing Jeremy's involvement with the farm. Pity that " piece of land " hadn't been discussed too,then Jeremy and all might have had an even clearer picture !
