Problem is there is provide and "provide".
Does living in a trailer park and claiming welfare and your children wearing clothes from charity stores count as providing? Never taking a holiday, never having a day out in the big city? Some might consider that not providing others would disagree.
What about being well off but so busy with running a business or being a corporate man you never spend enough time with your children? Their material needs are met but not their emotional. You say the rosary and take them to Mass and instruct them, but never build a castle from styrofoam and old packaging and pretend to be a dragon for them. This is not to say all business people or highfliers are this busy. I know of Traditionalist man who works hard in small bursts of a few days, earns much in that time and then behaves like he is semi retired until the next job, does chores around his home etc. His children and wife see more of him than most because he works from home.
These things are often subjective judgements. Here, in North America, few people ever actually starve. A Trad man could make a case that since his children are well instructed in the faith and don't have ringworm, or shingles, or malnutrition they are well "provided" for. Other people would look on a family on food stamps with pity and think it a shame that the father had settled for such a low baseline.
However, if the said father is using his unemployed status to take his children on daily hikes, capture mini beasts and study them, dissect plants, study the motions of the planets in the night sky then his children could be having a childhood to be envied by middle class children.
Most workshy fathers are not doing this though. They are smoking their home grown tobacco and waste their day posting their ideas and opinions in the Internet.
