her approach and the people that get chosen to be on the show are all about audience. The show would be really really boring if she was to come in take a look around and decide that they've actually got their shit together, retirement at 67 looks to be well on track, maybe they should make another fund for when that car starts to breakdown and if they decide to put an extra $20/month into the kids RESP's then the kids schooling is 100% funded.
Instead they show the extreme's people spending 3000% more then they make and to be fair they do with with both high income and low income families. This way the audience gets to feel superior to the family on tv because hell maybe we shouldn't have ordered dinner last night but damn at least I didn't buy another $500 purse that I don't need...
This is probably the reason they don't go the other extreme and show a mustachian family although I think it would be really interesting. Hmm lets see you save 50% of your income, have no consumer debt, the mortgage is almost paid off, you have a decent sized cash emergency fund, you're investing weekly in an appropriate mix of well diversified funds... What's she going to say, perhaps you should consider the tax implications of this investment and instead switch it to a different fund, maybe consider rental properties?
That would instantly look like gloating to 90% of the audience so it would never air.
