Volunteering for charity is very important. As is otherwise mandatory social programming – like education and military service / national service.
If you do the math, between spending 2-3 years in the army / sheirut leumi and the 32% chessed for National Religious, this community may have even more total hours dedicated to the kahal.
It’s also important to remember that volunteering is one important way to contribute, but it isn’t the only way to contribute. I hope the tsibbur remembers that just as they should be thanked for the chessed they do within and beyond their community, they should be thankful to the other parts of society that physically protect them, subsidize their healthcare, education, etc.
