'Tax' like most words, does not in fact have a real well defined meaning.

Remember how Pluto stopped being a planet because 'planet' went from just a word to a technical term with a well defined definition? Most words don't have that.

So, tax is any money given to the government. Income tax, sales tax, fees for registering cars, admittance to national parks, etc etc. Anytime the government collects any money that is a tax.

To paraphrase a great statesman---a lottery is just a tax with extra steps.
