The real point of difference is control of some people by others eg imperialism v masses.
In general control of land, its resources, means of production and distribution was always in hands of people individuals or groups who were powerful. They ruled masses as kings, as religious leaders=priests or as being bankers.
They made rules and laws and devised procedures and methods that secured their positions against the interest of masses.
Masses always agitated against them and chipped away their power and control bit by bit as time went on.
Masses also used similar ideas to fight for their freedom and so forced establishments give up some of their power. This tug-of-war will continue till it reaches a point where things become equally beneficial for all.
The quran has already told us that islam will succeed in the end not because of violent jihaad by mullahs but because education will become available much more widely and as masses will become aware of what is going on what should be done to make things better people will have no choice but to give way to peace. When people will look for peace between themselves they will need terms and condition upon which peace could be agreed and so the quranic predictions will find their fulfilment.
This is exactly what quranic islam is all about. Nothing at all to do with capitalism based secular democracy nor mullahs based islam that was invented by mullahs to make way and give security to some people from among muslims to be kings. This is why establishment always backed mullahs and mullahs always backed establishment.
This alliance will break down at one point and then will come about real understanding of real islam.
Islam is all about freedom, justice, fairness, compassion, brotherhood, progress and prosperity for all so that a society comes about that is good for humanity itself.
Islam is the goal set by Allah for mankind to achieve and maintain. The quran is the manifesto for islam so that people spread it and come together if they like the program laid down in it and so that they form a society based upon the quran as its constitution.
All this is a program to turn this world in to a paradise and also be awarded for doing that in hereafter as a result.
