Probably stating the obvious, but just because each full bitcoin is over $4000 doesn't mean you need to be rich. It doesn't change the price of items you purchase, so you just spend smaller fractions of each coin for each burger/hotel room/computer part.
If anything, the increasing price of btc (up to a point/limit) means that the consumer items are getting progressively cheaper, which would benefit both the rich and the poor.
What does this have to do with the OP's complaint? The issue is BSegwit's transaction fee is too expensive, which is expected since CORE is pushing Bitcoin to lightning network. So the on-chain transaction fee has to be expensive in order for lightning network to make sense.
