There are some things we can't do without in order to live the lifestyle the Tories want us to live in capitalist Britain.
I would argue the TV licence is not one of them.
Food and water is obviously needed.
Electricity is needed to cook and keep our food fresh, for lighting so we can work in the hours before/after sunlight and for work (increasing numbers of people are self-employed and work from home) and for looking for work (a computer, charging a phone, ironing clothes for an interview).
Internet access is needed for applying for jobs, for work - especially all those self-employed people - and often, for filling in mandatory forms such as tax returns.
Mobile phones are needed for keeping in touch with clients, employers, prospective employers (Tories would like anyone not currently working to always be "out looking for work" so if we only had a landline, we'd be missing phone calls).
TV licence is for entertainment and if we need to stay informed for work we have the internet. It's not needed, therefore it cannot be a tax.
So if any of these things could be described as a "stealth tax" it certainly isn't the TV licence. Right wing people who come out with this sort of claptrap think we're stupid.
