We don't do anywhere near as much as we could and I often feel powerless and ooverwhelmed by the world's problems
Ive also found as we have gotten more comfortable financially I've lost sight of things I was so passionate about when I was broke. I had 2 sponser kids and donated monthly to oxfam when I was a poor uni student, now we sponser a child and that's it, and I don't even know her name off the top of my head. Meanwhile, we spend $100 a month on stupid foxtel! (which I hate but husband insists). I buy second hand a lot, my family buy Tear or oxfam 'gifts' (like midwives, goats etc) for Christmas, I was volunteering teaching English til I went back to uni, but we could do so much more. The biggest thing is I try to raise my kids to be socially aware, but like you said refresh, they still complain which I find really sad.
I agree re the Vatican, when I went there I was in complete awe and felt very touched spiritually at st peters Basilica, but was sickened at the extravagance of it when so many people are starving.
