I think these people coming across the border have already been exploited by traffickers.
If there was no entry allowed for them, then they wouldn't be trafficked on the way to the border. Many don't make it, many women are raped.
Then when they do get in, what life is there as an undocumented immigrant? They are open to more exploitation.
You can solve this 2 ways:
- Just open the border and let them in legally, give them the paperwork and a path to citizenship
- Close the border so that the exploitation doesn't go on
The US Govt has been ignoring this issue, dropping a busload in front of the VPs error is political theater - it won't solve the issue - but it keeps it in the news. Neither party is offering any solution. Republicans want a wall, Democrats appear to want a free flow of immigrants.
Either way - it needs fixing.
