I want to introduce a concept to you. Imagine the country is your home. It is made up of the bricks and mortar, the roof, the inner walls and windows. It includes certain essential living items like a cooker, central heating, fridge, carpets, beds, furniture and within that we place our luxuries such as televisions, stereo system, food mixers, microwave, cutlery, glasses, wine, food, overseas holidays, new cars, dining out etc.
This is, of course, extremely simplified, but I just want you to consider a relatively simple analogy.
