Nixon is a good example... As I have already stated... Democracy shares bits of the same idea of accountability with Islam... Nixon had shot himself in the foot and lied blatantly and got caught lying... but as you yourself mention it is difficult to impeach the President... An ordinary man has no power to sue the President of the US in America... In the Caliphate if an ordinary citizen has a case against the Caliph... he can sue the leader...
Islam also has somewhat a similar system of
Executive: The Caliph and Assistant Caliphs/Governors of Provinces
Judiciary: The Courts and a special court to deal with injustice done by rulers called the Madhalim courts...
Council of Ummah: This includes representatives of the population who advise the Caliph on different issues...
However we do not have a legislating body because that has been done by the Quran, Sunnah and Ijmaa of the companions of the Prophet... as well as analogy... In cases where there is need for a new law the process of ijtihad based upon these sources of law (In Arabic law is called Shariah) provides for that... e.g the issue of cloning being a new technology has needed ijtihad... where there is more than one law derived, the Caliphs word is final...
As for your point about Capitalism providing the bulk of science and technology... There are a few points to consider...
Firstly science is not the fruit of Capitalism alone... Science is universal and stems from the desire of mankind to observe and learn about the world that surrounds him... Even the Communists produced new scientific ideas and interesting technology... Perhaps the drive for profit is greater than the stagnating idea of having collective ownership, but at the same time, Capitalism results in halting of progress in science and technology... Capitalism breeds monopolies and adopts ideas like Copy Rights and Licensing to prevent other people/companies to build upon technological advancement...
This can be seen in many fields like information technology but its effects are most obviously disastrous in the fields of agriculture and medicine... Copyrighting has caused much misery in the world by denying the ill of medication that can be cheaply provided to them...
A classic example would be that of medicine for AIDS... In fact interestingly for our Indian readers (and there are plenty on this forum), India long time ago adopted a policy of refusing such a copyright hegemony in this field and has been able to produce good quality medication for their own population as well as being able to export cheap medicine to other countries... It would seem someone in India simply refused to be budged by the powerful Pharmaceutical companies...
These are actually details and require an in depth discussion... If you want to know whats wrong with Capitalism in one main point, you need to consider this... Interest based transaction which is inherently a part of Capitalism is a recipe to make the rich richer and the poor poorer... Once people understand how this aspect of Capitalism enslaves most of the world, they start realizing why there is a need for an alternative system... Pakistan as a poor nation has paid back its original loan from organizations like IMF/World Bank more than 12 times over the original loan!!!! Similarly Sudan has paid it back 18 times over the original loan... Brazil similarly tens of times over the original loan... This is actually true for a lot of countries...
Similarly when profit making comes to a minimum in the business world... people start hoarding their wealth in banks to earn interest on it... For this very reason in times of a downturn banks reduce the rate of interest... because hoarding money in banks causes stagnation in the economy... Once people know that the only way to make a profit is by investing, they ll make use of their money instead of saving it to earn interest on it... this actually will provide more jobs and more activity in business... people of skills can open new ventures and entrepreneurship...
There are a lot of other things that are very oppressive in Capitalist system... The way government taxes people... One third of my pay gets deducted as income tax before I actually see my paycheck... There are all sorts of other taxes... VAT, Road tax, GST and God knows what else...
You misunderstood my point about individualism... in fact the examples that you have given of Wright brothers etc are exactly the examples that go against the concept of individualism... I m talking about individualism where every man thinks for themselves and does not care for others... What you are talking about are qualities of different individuals and there is nothing wrong with passion for invention and science...
If you look back in history, you ll find that the humanitarian aspect within western societies is actually a very new phenomenon and it was mostly as a response to the rise of Communism to prevent the people from getting influenced by Marxism which had found a home in Russia... We did not have the NHS here in the UK until after the second world war!!!!
A better example of individualism would be the happy slapping culture of the U.K!!!
Self interest is not setting up giant companies man... That is business... Self interest is rogue traders on the stock market!!!!
The state itself becomes a profit making machine under Capitalism instead of acting as a guardian for the people... which should be the real role of the state...
Now heres what I want you to do... Get a cold root beer my friend... and watch the following from start to finish...
