I'll be clear here, I do not approve of Trump's characterization of this caravan as violent thugs and criminals hell bent on invading and terrorizing the United States. It is ridiculous, politically motivated, and intended to play towards people's bigoted tendencies. The vast majority of these people are merely looking for the opportunity for a better life. I have no stomach for making these people the targets of our ire, nor treating them like war criminals, it is repulsive.
But to speak plainly, I do not see it as a good thing for the economic solvency and well-being of our country if we cannot reasonably control the flow of immigrants through our borders. We have laws that need to be followed, laws that establish order and are meant to avoid chaos. We cannot allow hordes of people to just show up on our doorstep and expect to be given entry simply because that is what they desire. It sets a dangerous precedent that our laws nor our sovereignty do not need to be respected.
I do not believe that economic hardship should be a qualifying condition for asylum. Asylum should be reserved for escaping genocide, political/religious/ethic oppression, and other forms violence. The vast majority of the people in this caravan would not seem to meet this criteria based on what I've seen reported. The majority of them are simply looking to escape places of economic hardship. That is not something I take lightly, but again, as unfortunate as it may be, I do not think it is practical nor prudent to let but maybe a small percentage of these people in based on the condition of asylum.
