What is most depressing to me (as a European) is the scale of
under-utilization of the IPv4 address space. Simply have a look at the
Hilbert map and check out all the black blocks (either ARIN or US corps)
and the most colorful blocks (either APNIC or RIPE).

Just one quick point on the above... It is unclear how much of the black blocks are due to under-utilization. The data was collected by utilizing ICMP traffic and many service providers block ICMP traffic. So, those black blocks could be due to lost ICMP probe traffic.
