You might read Politico Magazine's article on the subject (link and passages below). Politico is rated left leaning. But I think the article does a fair job of highlighting the issues surrounding immigration with respect to jobs and wages and to a lesser degree social services. It ignores the impact on housing and crime, but that was not the subject of the article.

Ignoring the truth, won't resolve the issues illegal immigration is having. I personally benefit from illegal immigration, but I realize my benefit is at the expense of those who have to compete with illegal immigrants for jobs and housing and that is not fair.

I am a big advocate of legal immigration including expanding today's quotas but using ways to screen immigrants to fill jobs where we do not have enough native workers rather than adding immigrants in sectors where we have surplus workers.

My position does not "favor" whites, in fact it was wealthy whites in the past, who supported open borders and historically Democrats who represented workers to oppose open borders... look at Clinton's and Obama's past speeches on illegal immigration.

As for divide and conquer, I am interested in what is good for Americans regardless of skin color. 70% of my grandchildren are African Americans (though they are unlikely to have to compete with illegal immigrants due to their educations), but that does not mean it's okay to ignore those minorities that do have to compete with illegal immigrants.

Read the article and tell me what you disagree with...

The linked article is 8 years old, so it is not about Trump vs Biden, but rather immigration policy and its impact on US citizens especially lower income Americans. Here is the link with some highlights...

"Trump might cite my work, but he overlooks my findings that the influx of immigrants can potentially be a net good for the nation, increasing the total wealth of the population. Clinton ignores the hard truth that not everyone benefits when immigrants arrive. For many Americans, the influx of immigrants hurts their prospects significantly."

"This second message might be hard for many Americans to process, but anyone who tells you that immigration doesn’t have any negative effects doesn’t understand how it really works. When the supply of workers goes up, the price that firms have to pay to hire workers goes down. Wage trends over the past half-century suggest that a 10 percent increase in the number of workers with a particular set of skills probably lowers the wage of that group by at least 3 percent. Even after the economy has fully adjusted, those skill groups that received the most immigrants will still offer lower pay relative to those that received fewer immigrants."

"because a disproportionate percentage of immigrants have few skills, it is low-skilled American workers, including many blacks and Hispanics, who have suffered most from this wage dip. The monetary loss is sizable. The typical high school dropout earns about $25,000 annually. According to census data, immigrants admitted in the past two decades lacking a high school diploma have increased the size of the low-skilled workforce by roughly 25 percent. As a result, the earnings of this particularly vulnerable group dropped by between $800 and $1,500 each year."

"Somebody’s lower wage is always somebody else’s higher profit. In this case, immigration redistributes wealth from those who compete with immigrants to those who use immigrants—from the employee to the employer." (note: I would argue consumers of services also benefit)

"When we look at the overall value of immigration, there’s one more complicating factor: Immigrants receive government assistance at higher rates than natives. The higher cost of all the services provided to immigrants and the lower taxes they pay (because they have lower earnings) inevitably implies that on a year-to-year basis immigration creates a fiscal hole of at least $50 billion—a burden that falls on the native population."
