I personally find it very interesting to unpack a premise that starts with the idea that "x is unfair", especially when it has to do with finance...if you can move past that basic premise to articulate why and how it is unfair, you can get to thinking critically about 1. personal finances 2. minimum wage employment and tipping culture 3. why taxes exist 4. how as a taxpayer you do have a real, tangible investment in the decisions made in your community and country
Using a Socratic approach to topics that may seem trivial can really open up conversations.
Let me restate my earlier comment.
1. Many tax laws are unfair
2. The government isn't interested in my opinion about taxes
3. The government isn't interested in your opinion about taxes
4. The government IS interested that you shut up, pay your taxes, and pay them on time.
5. The government gets extremely upset if you don't pay your taxes, if you don't pay them on time, and if you attempt any method of avoidance beyond the normative legal deductions and loopholes.
6. The government has a great deal of power with which to foist all manners of entirely unpleasant retribution upon those with whom they are upset... after which they STILL don't want to hear your opinions.
7. Therefore, though this conversation may be enlightening to the participants, it isn't going to result in the slightest change to any unfair taxes.
