Suppose you want to enjoy a lifestyle "of the medium":
You live with your partner in your house, you have got two kids, a dog, a cat, in a suburban area, have a got a middle-class job with good (but not exorbitant) income, you tend your own garden, you vote center, your life is neither stressful or exciting (like yuppies or hippies), nor is it rural and devoid of culture (like hillbillys). Your life is peaceful with small joys.
What is a good term for that in English? My inspiration for that question is the German term "Spießer", or the similar idea of "Biedermeier". In German, this concept has connotations both positive (balanced, comfortable, agreeable) and negative (narrow-minded, phony, stuffy), and provokes highly ambiguous feelings.
I do not even know whether or where comparable concepts like that exist in the Anglo-sphere. The stereotypical British lifestyle might be closest to it, and for North America, I don't know.
Q: How can this concept be made intellegible in English, including the highly mixed feelings about it?
