Middle income families spend a great deal more on their children and receive vastly less government assistance with a net cost of $375 per week and a lifelong cost of $449,513. The high income family spends $734 per week and receives, on average, just $1 per week in assistance.n our first report back in 2002 we found that it cost a typical family $448,000 to raise two children from birth until they left home (Percival and Harding, 2002). In our 2007 report we found that this cost had increased to $537,000 (Percival et al, 2007).
People with family incomes of $50,000 to $99,999 gave a median response of $75,000 â so, pretty close to what they currently make. The richest people to call themselves middle class, those earning at least $100,000, dictated that a middle-class lifestyle requires bringing in at least $100,000 a year.urvey respondents who called themselves middle class were asked how much they believed a family of four needed to earn to maintain a âmiddle-class lifestyle.â The median response they named was $70,000, though the response varied based on how much money the respondent himself or herself made.
