In today's world it isn't hard to have a million in "assets" if you include a primary and maybe a secondary residence. If you factor in property values at least in my area, it isn't that hard for pretty average people to have a very low 7 figure net worth.
But the way you are supposed to calculate net worth is subract your assets from your debts. So if you own a $1.2M house and owe the bank $1M on it, you should only count your $200k in the total.
Then the argument starts what should one consider an asset? That subject can be a whole new thread.
