Just being rewarded

This is one of the most interesting lyrics I’ve heard in a long time:

Again last night I had that strange dream,
where everything was exactly how it seemed...
No concerns about the world getting warmer,
people thought that they were just being rewarded,
For treating others as they’d like to be treated...
for obeying stop signs and curing diseases...
for mailing letters with the address of the sender...
Now we can swim any day in November.

- The Postal Service, "Sleeping In"
