WHERE CAN YOU make $2,000 a day, with no real effort? In San Mateo County, Calif.
Before you start packing your bags to head there, you should know that the average homeowner in San Mateo County saw the value of his or her property increase by $2,000 a day over the past month. The median price of a single-family home in the county reached $896,000. But if you don't own a home in San Mateo County, you don't get the two grand a day.
Someone from outside California might think that people must be building a lot of new mansions in San Mateo County. But, in fact, there is very little building going on there because most of the county is off-limits to building. These bans on building are known by the more politically appealing name of "open space" laws.
These housing bans are the reason for rising home prices.
Who can afford to live in such a place? Fewer people, apparently. The population of the county declined by about 9,000 people over the past four years.
Who is leaving - and who is coming in? By and large, young adults who have not yet reached their peak earnings years are finding it harder to afford housing in San Mateo County and in other such counties up and down the peninsula from San Francisco to San Jose. So they are leaving.
Schools have had to be closed because there are not enough children. The number of children is declining because people young enough to have schoolchildren are increasingly unable to afford the sky-high housing prices in communities that ban the building of housing.
People who are sufficiently affluent can afford to move into places with severe restrictions on building. Those who bought their homes years ago, before these housing restrictions were enacted, are able to stay while the value of their homes rises.
Among other things, this means that many young adults cannot afford to live near their parents, unless they live in their parents' homes. This isolates the elderly from their children, which can be a growing problem as the infirmities of age set in and their contemporary friends die off.
What has happened essentially is that those already inside the castle have pulled up the drawbridge so that outsiders can't get in.
Politically, this selfishness poses as idealism.
Much of this exclusionary agenda is pushed by people who inherited great wealth and are using it to buy a sense of importance as deep thinkers and moral leaders protecting the environment.
The foundations and movements they spearhead are driving working people out of areas dominated by limousine liberals, who are constantly proclaiming their concern for the poor, children and minorities.
The same wealthy busybodies who have made it an ordeal for less-affluent people to try to live on the San Francisco peninsula are now pursuing them out into the interior valleys, where the environmentalist foundations and movements are trying to get the same housing restrictions imposed.
This is not sadism - at least not in intent. These are green activists buying an artificial significance for themselves that they would never have had as mere inheritors of fortunes earned by others.
This is ultimately not about the environment but about egos. As T. S. Eliot said more than 50 years ago: "Half the harm that is done in this world is due to people who want to feel important. They don't mean to do harm - but the harm does not interest them. Or they do not see it, or they justify it because they are absorbed in the endless struggle to think well of themselves."
