You may not have noticed but that is over half of his pretax income. If people don't revolt over this then we are doomed because they will stand for anything.
Details were a little lacking. If 40K is total family income, the family would be eligible to be heavily subsidized on an exchange. Depending on age and number of dependents the bronze plan premiums might be zero and the cost sharing silver plan at a few hundred a month at most. $21K in premiums for decent unsubsidized family health insurance sounds about right..
