Be careful of this book and whether the author knows what he's talking about. (Otherwise, the typing of his manuscript and proof reading are way off.)
Big bubbles are easier to see than smaller ones – perhaps because so many more people are involved is something like the housing bubble.
If I have a few acres of land, and a supermarket chain wants to build an outlet in my town and I own the land that is ideal for them, then I can negotiate for the highest figure I can get. Probably very, very few people with hear/know about this.
OR (and it doesn't really work like this, because manufacturers make sure the workforce is there before they open a new plant), but imagine:
A big new car factory opens up in a town, and a lot of people move there to get jobs. They need houses. Suddenly, the demand for properties goes up and so do the prices. This might get reported on the local news, but probably not the national news. It's a local issue, small localized bubble.
But when a lot of people in a country want to buy their first home, and this demand exceeds the supply of properties available, then the prices of properties goes up and up; new buyers complain about the exorbitant prices, particularly if they can't afford to buy their new home and are squeezed out of the market; and that makes for good news: it will hit the headlines and 6 o'clock TV news. The nation knows about. BIG bubble affecting the nation and the nation knows about it!
