At the story's climax, the villainous Ratigan usurps the Queen of all Mousedom (and the empire, apparently) and starts bestowing decrees.
At 'Item 96' he declares that "A heavy tax shall be levied against all parasites and spongers, such as the elderly, the infirm, and especially little children"
I was quite surprised to find current Tory dogma so succinctly put in an animated feature from nearly 3 decades ago.
Ratigan dislikes being called a rat, despite the fact that he clearly is so, and refers to himself as 'Ratigan'.
Likewise, David Cameron deigns to present himself as a moderniser, despite clearly espousing a Tory ideology, and being a Conservative Prime Minister.
An old mouse responds to this new executive proclamation by protesting:
"This is ridiculous! You're insane!"
Which is almost verbatim my reaction, and I suspect that of many others, when I first read about the Bedroom Tax.
