His comments come as Greece and its lenders remain deadlocked in their debt negotiations.
Dennis Novy, an associate professor of economics at the University of Warwick in England, said Tsipras' statement has some truth "in that Greece was really forced to its knees because of the austerity program imposed by the IMF and European Commission.'"
Novy said the Greek economy has contracted by 25% since its last peak and that unemployment stands at about 25%.
"These are horrible numbers; they are Great Depression level, and Greece is in a big mess to some extent because of the imposed austerity. So I can understand there's a lot of anger on the Greek side," Novy said.
He added, however, that Greece is also responsible "for the mess that they're in."
Novy said it remains to be seen whether Greece can scramble the money together this month or if it defaults. He said that a Greek exit from the European Union is "becoming more likely day to day," but that doesn't mean it will happen.
"At the end of the day, it's still in the interest of Germany, France, and every other country of the eurozone to stay within the eurozone. Greece shouldn't leave, and Greece itself doesn't want to leave," Novy said.
He said the financial bleeding of Greece will continue, with the stock market down substantially and more people pulling their money out of Greek bank accounts, creating a serious risk of a liquidity crisis.
"Even if Greece does get a new bailout package in the next couple of days, this will continue for years and years, because of the trough the Greek economy is in," Novy said. In any scenario, there is no quick solution, he concluded.
