The problem with the other economic systems (including ours) is that they are not providing equal economic opportunities for everyone so individuals will not put of economic cycle by themselves but by the system, even if they didn't have the talent to compete with the others in the first place, so they will blame the system for their inabilities.
The only specific problem of Iran's economy that you cited as an issue was bribery, which is a form of corruption. I actually think capitalism can make it more difficult for people to have equal opportunities. In Britain there is a stigma against Private Grammar schools because they are expensive and their proliferation would mean only the rich could get good education. Building new grammar schools is actually banned in the UK. The UK also has the NHS, a public healthcare system which allows people to get proper healthcare regardless of their financial situation - again, equal opportunities.
BTW why you don't subscribe to capitalism?
Because I believe it creates too much inequality, it can be a cause of exploitation, and it has caused many of the economic disasters in the world, one of which was the 2008 crisis where banks were allowed free reign to pursue maximum profits with little regulation. Among other reasons.
What economic system do you recommend?
Socialism. Make no mistake, I'm no commie. But I show the Scandinavian countries as an example of socialism working well.
IMHO Iran's economy has 3 big problems:
1. Lack of an efficient fiscal policy. Tax collection is lacklustre, many taxes and subsidies are misplaced. Thankfully these are slowly being reversed from the Ahmadinejad era. Subsidising the oil industry in a country with 10% of all the world's oil is probably one of the stupidest fiscal decisions I have ever encountered.
2. Corruption. Bribery, "khodemooni", etc. are a highly inefficient allocation of resources and must be met by harsh policies by the central government.
3. Too many state owned companies. While I am a socialist, I think there are a few core industries that must be nationalised like railways, petroleum, healthcare, education etc. but there is a lot of unnecessary state ownership in Iran.
There are many other problems like high inflation (this is more of a symptom), overly protective tariffs, sanctions (more of an outside influence) but I don't want to be here all day.
The greatest thing about Iran's economy is its direction. It is moving towards a diversified, knowledge based economy. This is a great direction, but it is being hindered by the above problems.
