In America the average age of farmers is 58 because nobody wants to be a farmer anymore. There are farms in Japan that are empty because there is nobody to farm them; they are even experimenting bringing in workers from China, and they don’t like foreigners at all but they have little choice. The average age in Australia is 58. Canada has the oldest age for farmers in recorded history. In the UK the highest rate of suicide is in agriculture. I guess we all know that millions of Indian farmers commit suicide because things are so terrible.
More people in America study public relations than agriculture, because it has been a terrible business. The only that is going to change is for it to become very profitable and for young people to see the farmers getting rich. Of course they will say “those guys are driving Lamborghini's and I want one too so I will become a farmer”.
But it’s not going to happen until it becomes an exciting and profitable business. The Soviets tried to make people farm, they had all these coops or whatever they called them; Mao Tse Tung tried the same thing and eventually ruined Chinese agriculture by forcing people to become farmers. It doesn’t work.
The only way it works is for people to become motivated to become farmers and that will only happen when they get rich. There have been many periods in history where farmers got rich and powerful. It will happen again.
