It's interesting to compare the standard of living, infrastructure and services in countries in which people don't pay tax against those who do. Many people don't like paying tax, myself included, but Australia is generally a very comfortable and affluent place because of it.

There may be other ways to do it, rather than collecting tax, but in my lifetime I can't see anything replacing tax. I work to turning to my advantage as much as I can though, hence the accounting firm change.
