Actually, no. Obviously any immigrant set is going to be diverse. Contributions all coming on a spectrum from nothing to multi millionaire business starting.
The trick is to have a firm enough analytics handle on where you are as a country to handle all of the aforementioned needs of all of them that need it. You WILL eventually hit a point where you have to turn people away to break even economically . Then they start to come in illegally and you’re pushed past the breaking point.
How do you propose, in a world where we have that data (that may or may not exist yet I really don’t know if it’s possible to nail all of that information perfectly), that we handle the excess? If a church takes in too many people, they ask for more donations. If a country takes in too many people, who do they turn to?
The scope of the original statement was food shelter and healthcare. That’s a tall order for open borders with no concern for logistics.
Consider what the country looks like if conditions have deteriorated so much that it deters people from coming here. We will have zoomed past the equilibrium stage. What does life look for the average citizen much less immigrant at that point?
I’m sorry to wrap it up there but I only have so much bandwidth. However, these are conversations that people used to be able to have to tease out nuance, but somehow the zeitgeist has devolved to adversarial tone, name calling, and cultish behaviors. Hopefully I’ll find more when I have more time.
