Yes and farmers get enormous subsidies, taxpayers money, from the european union for instance, then so much is produced that the african market is flooded with produce while the farmers there can not sell their stuff for that low a price.
When boycot's happen like the resent one with russia, whole apple harvests were plowed under in fields.
Another example is that through regulation small farmers can not keep up with all the rules and go broke.

edit; It's a heavily subsidised and regulated market and lobbying by the government helps enormous, but everybody is lobbying by the government, every voter is a lobbyist in end effect, that wants to get money that is stolen from other people. Some are just more succesful than others, but all are greedy to get the money that others worked hard for, via government system.
