Supply and demand....
Company makes product
Product becomes popular
Company becomes successful
Employee becomes worth more - pressure on wages (inflation)
Employee disposes of more income - puts more money into the economy, buys imported goods, borrows more, more money chasing fewer goods (inflation)
Employee demands higher wage (inflation)
Employee buys bigger house - raises house prices (inflation)
Adam Smith mentioned the term "the invisible hand of the market"...it always sets the going rate for a product or service.
Eg. the Russian rouble used to be artificially linked to the dollar 1 for 1 but when the Russian economy was opened up the market found its true value.
