One of the things which made Bitcoin different from traditional wire transfers was that the fee for the transfer isn't related to the amount moved.

It's only related to the amount of data needed to record the movement. Moving a hundred dollars can cost more than moving a billion if the billion is in one utxo and the hundred is in fifty of them.

But with lightning the fee is related to the amount of liquidity in the channels used for the transfer, so we're back to the fee being much more closely related to to the amount moved.
