Data on the fact that the Haredim eat free food

I just read this article:

In short, a comprehensive study by the Kohelet Forum (no stranger to Judaism and the right) found that the Haredim are economic parasites who prey on all other Jews. You can argue about my language, but not the substance.
On the one hand, the conclusion didn't surprise me. On the other hand, the numbers surprised me, very large.
Perhaps the Rabbi would like to write about the implications of this and I would really like to hear his thoughts.
I'm here because the numbers are so large, that the issue seems urgent to me, to the point where every person needs to do something about this. What does the rabbi think the individual should do to turn this knowledge into change? It feels discouraging.
