I saw that when Gaza was turned over to them. IIRC, some liberal Jews in the U.S. bought a thriving nursery there from their Landsmen and gave it to the Palis "as a gesture of good will". Within days, if not hours, the place was dismantled as the locals stripped the place of everything of value.
The Muslims believe everything is a zero-sum game - no one improves himself until he can advance at the other guys expense.
It’s like a home of an African American women I used to know. She made something of her life. She earned a PhD and was successful. When she died of cancer, she left her lovely almost home free and clear to relatives. Rather than pay the property taxes and maintain the home, they trashed it and hauled off everything not nailed down. Even doors. The house quickly fell into disrepair. It went into foreclosure. Rather than cultivate their inheritance, they acted like leeches and parasites.
