I get your summary, but I don't think it's very fair that I have to pay this amount, its a fucking joke to be honest
The system should be structured on affordability, my own opinion is the singles reduction should be 50% but it won't happen as single people get fucked every which way with everything
I think you are looking at this wrongly
the whole council tax system is inherently unfair on everyone except the top 20% richest people
It cannot be reformed to be fair
it needs to be replaced by either a property value tax or a local income tax
personally i would go for the local income tax
