@Earl phil,
Rights are an infinite, as are all moral concepts... If pressed we can survive on far less than we expect, but that does not mean we should expect less than we have... We all know what rights we need for our well being... Whether those rights are rights or are privilages depends upon the conditions at the time... We cannot live without certain rights... We cannot thrive without others...If one person's privilage interferes with the rights of another then the privilage is no right...
