When people started believing capitalism's propaganda campaign proclaiming greed as good, capitalists as earning the money they stole, and poor people as lazy and stupid.
Capitalism like monarchy, and slavery tries to justify itself as the "natural order" of things. It's not.
1619, when instead of asking the natives for help, the future white Americans helped themselves to their land helped themselves to black enslaved people. How a thing starts is how it finishes. But, what do I know. I'm just a canary in this great big coal mine.
When did people equate “helping people” with authorizing government to loot and spend other peoples’ money?
You are free to “help” as many people as you wish, without government ... although it will be admittedly more difficult for you to virtue signal
