They are indeed not worth 'all that anger'- neither is the unemployed young man with 17 children by almost as many women. And the Press in publishing their stories as anger and indignation does make very good money.
And yet - why should we ignore that such cases do not help. It is clear that she has not had 11 children in a stable relationship, and then lost her partner to illness or accident. She has deliberately put herself in that situation, and expect others to pick up the tab. And it is not fair on those who do take responsibility for their actions and children, and then have to pick up said tab. The State does not pick up, but the people who pay taxes. Of course tax evaders, etc, are worse. But I really do hate this extreme duality of 'their scrounging in worse than mine, so mine is oK', kind of attitude. All kinds of tax evasion have to be tackled- and all are wrong.
