Results of our revolution in 1978

We have a large amount of underground reserves, then why public subsidies should be discontinued?Iran has a large amount of oil, gas, uranium, radium, pistachio, saffron, carpets and handicrafts for export. The Iranian government claimed that developed countries are governed by paying taxes.
Is there any underground resources and exports in all developed countries like Iran ?

Do they tax? (the people of Persian Gulf countries)Does People give taxes to the government whether a country has oil and gas?Do you know which country that his government could have plenty of resources for income, and  take a lot of taxes from people?

Iranian politicians are receiving  taxes from the people,  and subsidies are cut and they spend the revenue from oil and gas sales for himself and terrorist groups in Lebanon and Palestine and Afghanistan. That means the country will be run by tax money from people and terrorists will be run by money from selling oil and gas in Iran.Whether is this the result of the revolution in 1357?
