Not sure I agree. How do you explain Sam Walton? Born to a family of poor dirt farmers and raised in the Depression. Early jobs included waiting on tables and a paper route. Yet he built Walmartinto the largest retail chain on Earth. All BECAUSE of capitalism.
No, everybody won't make it to the top. But the point is EVERYBODY has an equal chance regardless of background.
Sounds good in practice, but the reality is that for one who even moderately succeeds, 10,000 don't and just get by.
Frustration and resentment build. Society no longer has 'know your place' indoctrinated into it, thankfully, and the constant encouragement to buy, borrow, and have it all hype just adds more pressure.
No getting away from the reality on the ground, which is just so far beyond decent behaviour that those people cannot be considered anything but criminal now, but it is the understanding and easing of the social deprivation that will stop it happening again.
There are no jobs, not even waiting on tables, poor people don't get papers delivered, and those wealthy enough to do so have long established newsagents who are picky over who they employ.
When the bills coming in for rent, fuel and food overwhelm any attempt at budgeting, not just for the occasional week, or month after month, but for years at a time; the young scorn the rules of do not steal, do not damage property, etc..
It's not just a London phenomenon, but a worldwide one. That it is happening in a socially benevolent society is the biggest shock.
We do provide free at the point of treatment healthcare, for everyone.
We do provide social housing, though that's no longer available for all, but social services will provide rent and rates for those whose income falls below certain levels.
We do provide for those with young families.
We do provide good free schooling and meals for those in need, and clothing allowances.
Too many though, even with those aspects taken care of, are stuck in a no hope of change or improvement lifestyles and constantly bombarded with images of those who have it all.
Of all the hype of the folks who claim that benefit mentality needs to be destroyed, damned few live in inner city schemes and towerblocks where even our quiet wanders into countryside are totally unknown.
I work in an inner city area at times; folks are really the salt of the earth

but you know what their kids want to be when they grow up ?
Drug dealers.
Because the drug dealers are the only ones in their society with money. Rolls of money in their pockets, designer gear, bling, respect, fancy cars, posh stuff in their houses, influence, holidays......
How do the police fight that ? It's engrained in their society.
Easy answers would be wonderful, but there aren't any.
With any luck the rain will drive them home and let things cool down, and then we see what new restrictions are going to be imposed on everyone in response
Heartfelt sympathy for those who don't want to be involved and have no choice.
