Of course not. Abdi the neurosurgeon probably went through the process of getting a visa, moving to the country legally, applying for permanent resident or citizenship status, and paying taxes on his own tax ID number. Abdi the neurosurgeon is the immigrant Kate isn't worried about. Kate without a degree is probably a little more worried about the unskilled person who crossed the border illegally, works low-skill labor under the table, can't get a driver's license and so may drive unlicensed and possibly uninsured, and doesn't have access to SSN-required healthcare and so may end up draining thousands of dollars from emergency care (life-saving emergency treatment is guaranteed in ERs, preventative care is not) if something bad happens to them. In reality, Kate doesn't have to worry about either because neither is actually taking her job, but Abdi the neurosurgeon should probably be a little pissed that he did everything right to get here and somebody else just walked across a border.
if there are a millions unemployed Americans and a million illegals immigrants employed and no jobs available yes they are stealing jobs maybe not good jobs but a bad job can feed your family.
Simultaneously being lazy and stealing your jobs
