How does Douglas Adams use satire in The Hitchiker's Guide to the Galaxy?

Adams used satire in The Hitchhiker's Guide to
the Galaxy to show the absurdity of modern life, and how things that we
consider of great importance are actually insignificant in the larger scheme of things.
For example, Arthur is worried about his house being destroyed for the construction of a
highway bypass; this problem becomes unimportant when the entire Earth is destroyed for
much the same reason. Many of the situations mirror situations, events, or institutions
on Earth, but are exaggerated for comedic effect. Galactic bureaucracy is shown to be
staggeringly inefficient and bloated, with the Vogons being an entire race of
inefficient and bloated creatures whose sole purpose is to help block progress and
create paperwork. The destruction of an entire planet (Earth) is seen by alien races as
unimportant; on a galactic scale, planets and races are destroyed every day, and so
Arthur's concern is mocked and ignored. By using easily-identifiable scenarios, Adams
was able to show the absurdity in everyday life, and how constant worry over small
issues is counter-productive.
