My 2 cents.
If you look up all of these companies, State Farm, Geico, AFLAC, Allstate, Prudential, etc etc...look at the pictures of their corporate headquarters. Where do you think that money for the wasted space marble floored opulence comes from? You and me! Then there are all of the buildings around the country with an insurance company name. The GEICO Arena..The ALLSTATE Arena. Insurance companies are similar to banks. Both are intermediaries of funds. If you have $100,000 the best bang for your buck is to loan it to someone. But what does the average depositor know about making a loan. So, we loan it to the bank, and they turn around and use their lending expertise to re-lend it at a better rate. (any deposit in a bank is in its most common denominator, is a loan to the bank) They owe you the money, sooner or later. Insurance companies also make loans, however usually in the form of real estate investments, home mortgages (Washington Mutual come to mind?) and other instruments of funding. A whole-life insurance policy is simply a loan to the insurance company. The re-invest the money while you are alive. Life insurance is probably the least denied insurance claim, but they still make your beneficiaries prove beyond a shadow of a doubt that you are dead.
My experience is that they will try like heck to get out of paying a claim. However, they have the insurance regulators to answer to, especially on consumer claims, which is the reason for the meeting where they make an effort to pay. It looks good to the insurance examiners.
