It will be a slow decline ,Cong's I have been in about 1/3 are 65 + in age so in the next 10-15 the number will decline because of natural course and as born ins are leaving in their droves and others wake up because of the internet and the exposure of the falsehoods and lawsuit's the numbers will probably half in the next 10-15 years.
Then only half the money or those that are left will have to pay double.
