Also, no idea what consulting firms do, clearly.
If you have pets bigger than a hamster, 70k in your lifetime seems reasonable, even low. That around 1k per year.

I don't see the data to be so bad. Even the house financing is realistic (heavily dependent on location, of course).
Neither does anyone on here, but at least you don't deny it :)
