I agree others will follow suit, maybe not the next new product / pricing rolling out but very soon. Just like with removing lifetime benefits, limited pay options, the other carriers couldn't get their changes out fast enough once Genworth announced.
When companies discover a way to pad their bottom line, they will do it. I don't see the insurance company being any different as you have already mentioned TriciaS.
They are no different than the airlines who jumped on board making us pay for checked baggage and more room in seats. I remember when I was a kid no stores were open on Sundays and banks were closed by three and closed on weekends. As soon as one of their competitors changed and began making money, others in their industry followed as long as money could still be made.
Let's not fool ourselves folks.
