Why can't everyone who wants to, enter the USA illegally?

Why can't everyone who wants to, enter the USA illegally? A response to a video that a young woman posted on X.com, asking why everyone who wants to live in the USA just walk over the border illegally?
Short answer:
1. The USA is bankrupt - we can't afford it.
2. There's not enough food.
3. There's not enough housing.
4. There's not enough medical care.
5. Many of the people entering are criminals, who seek new victims.
6. Many are literally foreign invaders.
