As a Canadian this whole TV tax and the costs to enforce and prosecute it is absolutely absurd. No matter how much money they collect I am willing to bet that the true costs for the investigation, prosecution and collection is at least 30% of revenue.
The BBC I think is probably a lot like the CBC (which is government funded) and the CBC is paid for in some way or another through our national taxes.
You can't tell me that it would not be smarter (and ultimately cheaper) if they just added $100/year to everyone in the UK's income taxes (considering there are 65 million people in the UK, 32 million working according to the labour stats) and they could probably drop that cost considering there would no longer be an enforcement or prosecution costs.
Its not like taxes in either country don't already pay for services that we don't use (I for example pay for a public school tax even though my kids don't goto public school). Its the "everyone pay's a little so that everyone has access to the services even if they don't want to access them" civilized mentality.
However, as I was writing this I was reading how much money this TV tax collected and I almost had a kitten. How in the holy name of hell does a television company get away with a 4.827 Billion dollar budget in 2015- https://en.wikipedia.org/wiki/Television_licensing_in_the_United_Kingdom)
The CBC by comparison (lets not debate quality of programming or anything) is government funded to the tune of 1 billion in 2016 to make up operating shortfall. We have about 18 million employed people here so technically we are paying about $55/year or so on income tax to support the CBC.
No private investigation company, no judges to pay to enforce the individual tax, and no one needed to try and collect a judgment.
