"Avoidance" is not the word used by normal people. That's a word only used by tax-evasion consultants (and their clients) to euphemistically refer to what they're doing, which is gaming loopholes (many of which they have themselves lobbied to have added to the laws).
Sure, it implies they're scum! That was intended. I'm not going to correct it by using some newspeak bullshit that no regular humans use, like "tax avoidance". This isn't a corporate prospectus! I have never heard a regular person use the term "tax avoidance strategies", only consultants who are trying to differentiate their brand of tax-evasion (technically legal!) from the other brand of tax-evasion.
