You ever bought carrots from the supermarket? Why? You could by your own right? And you don't pay taxes on the carrots. It's a 0 VAT rated item (like most fruit and veg) but you do pay for them. That money goes to the shopkeeper, the shopkeeper pays the staff and the carrots themselves are bought from a farmer who specialises in growing carrots.

So why do you buy carrots from the shops when you can grow them yourselves?

Because other people can grow more of them better and with different kinds. You get a choice from the shops that you don't get when you grow a few carrots at home. There's pretty much carrots in the shop all the time because there's a demand for them and you don't have to wait 6 months to get your carrots out of the ground.

And Britain is more like America than you think chum. You think that there aren't different states then why is there English/Scottish/Welsh and Irish law?

Also. If you paid attention to economics in highschool you'd understand free markets and the black market and why we want one and not the other.

And if you want to say something's fact then prove it boyo. Otherwise keep chewing your lip.
