For those complaining about 'high' #XRP transaction fees.
@XummWallet does not take the fees. They are burnt.
If XRP was US$1 and the transaction fee permanently set to the 'medium' level of 15 Drops (00.000015 XRP), we can still do 66,666 transactions for a penny.

The base fee of 12 drops (a drop is one one-millionth of an XRP) allows for >83000 transactions for US$00.01.
The fee structure is intended to price out spammers, eventually making it too expensive for them to continue spamming the network.

There is discussion among developers about the effectiveness of that design choice and if it is the best way to achieve that goal (without punishing legitimate users)
Even with higher fees, the XRP Ledger is one of the fastest and least expensive blockchains of any size.
