Everywhere you look in contemporary America you see a people engaged in the pursuit of happiness. You can see it in work habits. Americans on average not only work longer and harder than most Europeans, but endure lengthy commutes to and from work. You can see it in geographical mobility. About 40 m of them move every year. They are remarkably willing to travel huge distances in pursuit of things like bowling conventions and so on. And you can see it in the country’s general hopefulness: two-thirds of Americans are optimistic about the future.
Since Americans are energetic even in deconstructing their own founding principles, there is no shortage of people who have taken exception to the happiness pursuit. They range from conservatives like Robert Bork, believing the phrase summarizes the "emptiness at the heart of American ideology", to liberals who think that it is a justification for an acquisitive society.
One criticism is that the pursuit is self-defeating. The more you pursue the illusion of happiness the more you sacrifice the real thing. The other side of mobility is turmoil and anxiety, broken marriages and unhappy children. Americans have less job security than ever before. They even report having fewer close friends than a few decades ago. And international studies of happiness suggest that people in certain poor countries, such as Mexico, are apparently happier than Americans.
Another criticism is that Americans have confused happiness with material possessions. It is notable that Thomas Jefferson’s call echoes Adam Smith’s phrase about "life, liberty and the pursuit of property". Do all those pairs of Manolo Blahnik shoes really make you happy Or are they just a compensation for empty lives like in the soap opera Sex in the City
If opinion polls on such matters mean anything—and that is dubious—they suggest that both these criticisms are flawed. A 2006 Pew Research Centre study—"Are we happy yet"—claims that 84% of Americans are either "very happy" or "pretty happy". The Harris Poll’s 2004 "feel good index" found that 95% are pleased with their homes and 91% are pleased with their social lives. The Pew About sponsorship polls show that money does indeed go some way towards buying happiness. They also suggest that Americans, devotion to religion makes them happier still.
The pursuit of happiness accounts for all sorts of peculiarities of American life: from the $700/m spent on self-help books per year to the irritating dinner guests constantly looking at their BlackBerry cell phones. This pursuit may even help to explain the surge of anti-Americanism. Many people dislike it precisely because it is doing exactly what Jefferson intended. For some Europeans, the pursuit of happiness in the form of monster cars and mansions is objectionable on every possible ground. You cannot pursue happiness with such conspicuous enthusiasm without making quite a lot of people around the world rather unhappy.
We can infer that Thomas Jefferson and Adam Smith

A:mistook material wealth for happiness. B:did not share their views on the happiness pursuit. C:criticized the pursuit of happiness. D:believed life, liberty and material pursuit were equally important.
