How immigration contributes to job growth and demand

People have been saying that immigration is a problem since USA began, and other countries too.... seriously I have worked with so many positive hard-working people from other countries that I welcome them. Many people I know even want to marry them because they are happier and kinder than many of the people, they know from the USA.... If a person is afraid of someone taking their job, then that person has to work a little harder to be good at their job.

America is what it is today because of families who immigrated, except the Indigenous and there are some that say they too migrated even if it was thousands of years ago. The problem isn't immigrants, it is the political system that has a lot of corruption and control over media which keeps pushing people to hate one another while most of our kids are under-educated, health care costs are high, food is unhealthy, many don't have enough to eat, and a lot are not even sheltered.
