In which world do u live. It's like when you go to a restaurant, you count the value of the ingredients if the food you get . . . :)
Take it easy brother ;)
That's like walking into a restaurant, and saying Wow, what a ripoff, you're charging £25 for that meal, but the ingredients only cost £5.
It's not the parts that make up the total cost of the item, it's the R&D, manufacturing costs, etc.
