In some states the people who sit in the parliaments have very little interest in changing the present system, are themselves (still) beneficiaries of the system and are also often caught up in dependencies and contraints themselves.
I myself have often experienced this in talks with government representatives, economists, presidents of central banks etc.
They mostly have no idea how to organise a debt-free and interest-free monetary system in their states. Neither do they know what freedom and prosperity that would lead to for all people, without anybody being a loser. Nor do they know how to establish a nationwide health service offering all people a right to health and actually also implement this.
They do not know of ways to create a pension system which works independently of the demographic development and provides all people with a secure and prosperous old age in happiness and esteemed by others.
