To want everyone's earnings and tax records to be public information

[Itsgonnabeacoldone]

I think it would be very modern and progressive if the UK government changed the law to make people's income and tax public information. Would probably raise a few billions more and make people less likely to do those dodgy tax avoidance schemes.

Yes, you are being completely unreasonable. It would raise a myriad range of problems, including good earners who have parasites for relatives having a miserable time trying to fend off begging requests of "oh but I know you can afford it", fraudsters finding targets more easily, all kinds of things like that.

Wanting everyone to pay their proper taxes is a different ball game entirely. But the way to do that is to cut down on the legal opportunities for tax avoidance, and to actually go after people more aggressively for tax evasion (not the same thing as tax avoidance), because ATM if you get caught for tax evasion HMRC rarely prosecute because it's so expensive, they just make you pay the extra tax you owe, so a lot of people perceive it's worth the risk...
