So Roman Catholic doctrines regarding sex and birth control had nothing to do with it?
The catholic doctrines account for some of it, across the world, basic grinding poverty, the mud hut variety, and corrupt governments, war and famine play their part. Have you noticed the amount of Adds on TV that originate in far off lands, all involving kids, and their mum's, where pray, is dad?
Poverty takes many forms, here in the UK your considered poor, if you do not have at least 80% of the basic wage to survive, which is about £25K. We had 6 kids, i wasn't earning a lot, we managed, went without for many years, no holidays, no car, no big TV, or SKY service, and when first married, no washing machine, fridge, freezer, tumble dryer, dish washer, or landline phone. all this was before mobiles were invented. This put me on the poor list, by the standards of the day, , but I didn't consider myself poor, as I had a roof over my head, a job, and could pay the bills, and the kids didn't starve.
Poor is relative, My income is just fractionally above that which would allow me to claim pensions benefit, But by the standards of today, if i was working, that amount would class me as poor.
The days of grinding poverty that my father (93) had to endure in the mid 20's in the dockland area of London's east end are long gone, bare footed scruffy half starved waifs no longer exist in the UK, and if they do, its caused by parental abuse and cruelty, and not financial circumstance.
The Poor do exist, Fact, and they always will, and all the legislation, laws, and good will by men and women of high moral compass working on their behalf will never alleviate it. Church state and class divide, the three reasons it will never vanish.
