Huge Protests in Israel

Four hundred thirty thousand people demonstrated across Israel on Saturday night. Israel's population is 7.7 million. If 770,000 people are about ten percent of the total population, that means about 380,000 people would be five percent, that makes 430,000 people, what?, close to six percent of the population. Is that right? Even if I'm wrong, the numbers are HUGE. And what are they protesting about? The cost of living; the salaries of teachers and policemen; the concentration of wealth among an elite few families. Good golly it's heartening.
