I think most of the earlier hunters and adventurers,specially the hunters belonged to rich families.In India hunting was a sport of Nawabs,Princes and ofcourse the British.They were well equipped according to the times and every facility was available to them.Later when hunting became quite common and the average person could afford it,it became became more adventurious and difficult.When i hear of how my forefathers hunted i envy them because they did not have to rough it out as we sometimes do.In the case of Africa its different because its all arranged and as you said the animals are fenced and the PH is there to look after you,not so in other places where you have to stalk game, sleep in the open and make do with bare facilities.
All in all i'd say its not all that easy or luxurious now and i for one would like to do it as in the days of old.
