I'm far more liberal than most people. I mean that in many different ways. I'm a free thinker. I believe in personal liberties. I don't tow party lines. I don't think anyone should. I also don't think that people should just be able to keep people from moving where they want to. I think people should be able to move to other countries. I think that the ability to migrate is a liberty. I don't think we should be wasting money paying for stupid shit to keep people from moving to another country and contributing to the economy.
You can argue that some immigrants may be dangerous...but statistics don't agree with you. On the whole, they are less dangerous than natives. They don't wanna get in trouble, because they can get sent away.
Theoretically, people that will eventually commit acts of terrorism could possibly come across a border, but should we really treat everyone like criminals because one out of millions MIGHT be one? It's just kinda crazy.
We should be welcoming immigrants into the country, and giving people grants and loans to start small businesses, and making it easier to run them, so they can give jobs to everyone.
We don't have problems with jobs because immigrants are stealing them. They take some jobs because employers can pay them less, illegally, but is that the immigrants' fault? No. It's our system's fault. They should have to pay them a minimum wage like everyone else, and they should be paying taxes on that income. In fact, many immigrants do pay taxes, with no way to get back what they pay into the system. So they pay way more thna they need to, and can't get a tax refund.
They come here, work shitty jobs, just try to survive and have a better life than wherever they left, and contribute to society. Why is that so bad? Because they might fill a job for cheaper than you're willing to work? Why is that so bad? How is that the immigrant's fault? They are just trying to survive. Why do we have this mentality lately that there's something wrong with them. They have built nations. Migrant worker are good for economies. We need to produce more high paying jobs, not lament about people taking shitty jobs we don't even want.
