This isn’t a terribly helpful anecdote. There is plenty of ongoing research into why there are higher rates of allergies in developed countries. I’m sure early exposure to allergens help (and is AFAIK recommended practice now) but other things play a part - I’m sure I saw some research recently suggesting that one reason developed countries have higher allergy rates is due to lower prevalence of parasitic worm infections. The natural world is complicated.
