Well Areivim is even more underinsured (unless a person had more than 9 children) in which case they are certainly underinsured with 1 million of coverage.
Insurance agents love to sell bigger policies, but the point of life insurance (from a financial planning perspective, as I see it) is not to make the family whole from the financial impact, just to limit the downside, so they are not impoverished. After all. the premiums are expensive and priced to be in the odds of the insurance company (so life insurance is a bad bet to make from a purely financial perspective), except that it's a cost too high to bear, so one needs to make the bet (policy) for protection.
Getting more than $1 mil., becomes quite expensive, especially if insuring both spouses, and when considering cost of other insurances (homeowners and car). That can easily run $5K+/year combined, just on insurance.
I pay $584 a year for 1 million 30 year term for my wife, and $1,400 for 2mm 30 year term for myself. It's money but relatively affordable.
