Presumably, it's people's business because the US is basically a nation governed by the people who see it as their responsibility to help ensure their basic values (peace, prosperity, life, freedom, justice, pursuit of happiness, etc.). So, when there's regulation that affects the people, it actually is their business.
The people who own businesses are US citizens.
If bringing people from outside the USA into the USA puts people out of work, doesn't having children also put people out of work?
