So, smoking got more expensive for me lately. Normally my favourite brand of tobacco and a package of papers set me back 8 Euros, a few weeks ago it went up to 9. Now I assume this is because of increased taxes. And that got me thinking. How much does it cost to manufacture my tobacco. Which part of those 9 Euros is just the costs from raw resource to the vendor. How much is the margin the company put on it. And how much is tax? Then I thought about other products. How much is the cost, how much is the margin? Is the value of a product whatever a fool is willing to pay for them? Is that a fair price? Do the laws of supply and demand used to create the largest profit for a company determine a fair price? And if this is the case, is it so strange of me to ask the producer what kind of margin he gets from the product I'm buying? After all, if a company can probe it's consumers and tweak their prices for an optimum profit margin, and we agree that's a fair deal since companies are supposed to create that optimum to guarantee continuity, should I not be able to make my decision on which product to buy, be just as informed to make the best decision? Of course I realise this creates margin buying where people shop for products which price is closest to the cost price so that they have to pay as little as possible extra, but I'm not asking for practical issues, I'm wondering: what's a fair deal? I can imagine the answer to the practical point of view could be: (No, it's not fair, but the fair way/Yes of course it's fair and your system) would spell disaster for companies. Just: Do I have the theoretical right to be informed of the way the price of the product I am buying came to be? Just as I have the practical right to be informed about the ingredients of a tin of food, or the BHP a car produces. The question is puzzling to me, so, do I?
