Illegal immigration brings masses of people from more corrupt, disordered, and perhaps lower average intelligence societies into the US in conditions that make it hard for even the ones who are capable of assimilation to assimilate. It also constitutes a massive flouting of the law for the benefit of business, which sets a bad precedent and lowers public trust in institutions. It also contributes to rising racial tensions that encourage the growth of ethnic tribalism and weaken trust in liberalism.
