Unemployment among the youth has reached a record-high of roughly 31%, while approximately 60% of the Iranian population is under 30 years of age.
President Donald Trump begins a series of tweets about the protests: "Many reports of peaceful protests by Iranian citizens fed up with regime's corruption & its squandering of the nation's wealth to fund terrorism overseas". "He's not going to want to waive sanctions and keep money flowing to dictators when there are people protesting in the streets", Richard Goldberg, a former Senate Republican aide who participated in designing sanctions against Iran, told Politico.
Late on Wednesday, senior Trump administration officials acknowledged their surprise that the protests took hold so quickly.
The working-class anger behind a week of unrest in Iran will pose an increasingly potent challenge to Tehran's ruling clerics as economic and social pressures mount, even if the current protests peter out, analysts said Wednesday. These protesters, who are flooding the streets and demanding that their voices be heard, are committing acts of heroism that will be felt throughout the world and throughout history. "We encourage all parties to protect this fundamental right to peaceful expression and to avoid any actions that contribute to censorship". Rouhani promised greater social and political openness, as well as a revived economy after years of worldwide sanctions, but he has been unable to deliver much change in a nation where the ruling clerics must approve all major decisions. Unemployment in Iran is about 12.7 percent, and the cost of basic goods jumped 40 percent in 2017.
The unrest has also further increased tensions between Tehran and Washington.

At least 20 people were dead as of January 2. The government suggested that foreign powers were behind the protests and promoted loyalist counter-demonstrations.
"Iran's growing nuclear activities and its remaining nuclear infrastructure will have been granted legitimacy by the global community, its defensive and offensive military capabilities will be greater, and the United States will have agreed not only to refrain from imposing additional sanctions on Iran for nuclear advances but will also have suspended its most significant sanctions". Gen. Mohammad Ali Jafari.
