No, its not a consumers choice. It is the law. As the owner of a landscape company, I am required to be licensed and carry liability and workers comp. From reading your posts, you seem to be justifying illegal behavior. So using your logic of 'they're here so let them stay', let's not chase speeders or arrest bank robbers. People are always going to do it, so don't enforce the laws.
In my opinion, the borders can be enforced and illegal immigrants can be deported. First stop all pork barrel spending projects. That is not what my tax dollars go towards. Second, stop sending aid to foreign countries. Neither of these things are mentioned in the Constitution. The money that is spent in these two areas is more than able to pay for the proper number of ICE agents required to complete the task.
If you think it can't be done, think again.
