Our fondness for stuff affects almost every aspect of our lives. Housing size, for example, has ballooned in the last 60 years. The average size of a new American home in 1950 was 983 square feet; by 2011, the average new home was 2,480 square feet. And those figures don’t provide a full picture. In 1950, an average of 3.37 people lived in each American home; in 2011, that number had shrunk to 2.6 people. This means that we take up more than three times the amount of space per capita than we did 60 years ago.

Apparently our supersize homes don’t provide space enough for all our possessions, as is evidenced by our country’s $22 billion personal storage industry.

What exactly are we storing away in the boxes we cart from place to place? Much of what Americans consume doesn’t even find its way into boxes or storage spaces, but winds up in the garbage.

The Natural Resources Defense Council reports, for example, that 40 percent of the food Americans buy finds its way into the trash.

Enormous consumption has global, environmental and social consequences. For at least 335 consecutive months, the average temperature of the globe has exceeded the average for the 20th century. As a recent report for Congress explained, this temperature increase, as well as acidifying oceans, melting glaciers and Arctic Sea ice are “primarily driven by human activity.” Many experts believe consumerism and all that it entails — from the extraction of resources to manufacturing to waste disposal — plays a big part in pushing our planet to the brink. And as we saw with Foxconn and the recent Beijing smog scare, many of the affordable products we buy depend on cheap, often exploitive overseas labor and lax environmental regulations.

Does all this endless consumption result in measurably increased happiness?

In a recent study, the Northwestern University psychologist Galen V. Bodenhausen linked consumption with aberrant, antisocial behavior. Professor Bodenhausen found that “Irrespective of personality, in situations that activate a consumer mind-set, people show the same sorts of problematic patterns in well-being, including negative affect and social disengagement.” Though American consumer activity has increased substantially since the 1950s, happiness levels have flat-lined.

I DON’T know that the gadgets I was collecting in my loft were part of an aberrant or antisocial behavior plan during the first months I lived in SoHo. But I was just going along, starting some start-ups that never quite started up when I met Olga, an Andorran beauty, and fell hard. My relationship with stuff quickly came apart.
