I never said they could...

You cannot deny that the capacity of the network has increased significantly from the past. Segwit has made transactions smaller and increased the theoretical total transactions per block. Lightning network has allowed for 2nd layer transactions. It has by no means stopped the high fees problem; adoption rate is way too low and its no silver bullet either.

As of now, the fee is approx. ~60 satoshi/byte for a reasonable timeframe which gives the total transaction fee of a normal transaction to be $0.50. Isn't that cheaper than a lot of the payment processors?
