Globalisation has to some extent brought us prosperity but it has also brought us cartels and monopolies. Some of these companies have grown so big through the spread of globalisation that they are now very difficult to challenge and so have a virtual monopoly. Facebook, for example, has little competition. There are alternatives in China like QQ but in the western world, Facebook has the power to dominate the market.
In theory, competition and supply and demand should regulate prices in a free market. In practice that isn’t the case. There are monopolies and cartels. There can be a lack of competition. There can be government interference in the market, such as the government’s ‘help to buy scheme’; that can distort the property market. An increased money supply can also mean increased demand.
Imagine living in an English country village, surrounded by farms where all the fresh food comes from. You can go to the local farm market in the village and buy fresh food from lots of different farmers. You would probably shop around to get the cheapest meat and vegetables. You might eat whatever is in season and take advantage of availability and low prices. When there was a glut of apples, because of a good harvest. You would be able to buy lots to make chutney and apple pies.
