I have no sympathy for businesses that exploit the labor of illegal aliens. They are a cancer that depresses wages for US citizens. The cancer needs to be removed. I am confident the voids left will be filled.

also, the jobs are usually back filled by citizens and legal workers.

First, ICE is going after illegal aliens. Businesses hire illegal aliens because they can pay them less than a US citizen, usually below minimum wage, and without healthcare, social security taxes, or unemployment benefits. You're advocating for these businesses to take advantage of these illegal immigrants. The argument you are making is like a pre Civil War southern saying "Who will pick the cotton if we free the slaves"

so you're for paying workers below minimum wage?

JeffreyHornick made the point better than I could. Why didn't Trump deploy the Guard on J6? Because unlike the liberals believe, he is not a dictator and he was deferring to the sergeant at arms and the capitol police. He learned his lesson.
