Her comment was being targeted at the upper class who are the loudest ones yelling for this. There's also a fair amount of 'working class' industries who rely on migrant workers to keep labor down, such as landscaping and house cleaning. This is what the tweet is hammering at.

Keeping the price of labor down is exactly what they're talking about. She knows that illegal immigrants providing cheap labor won't affect her wages and allows her to hire people to do manual labor for dirt cheap, so she accuses people of being xenophobic racists if they aren't fine with exploiting illegal immigrants to provide cheap labor.

Huh? She's trying to highlight the hypocrisy in people who want border walls but then demand those services at cheap rates. This is nothing specific to her own thinking and want of cheap labor. It's purely calling out the conflicting stances.

And once again the kind of people who hire others to mow their lawns or deal with their kids won't have their own wages affected by the cheap labour those illegal immigrants will bring.

Speaking of fairness, why exactly should we have more concern about the job prospects of someone who happens by random chance to be born on one side of a border than someone who happens to be born on the other?

If anything, isn’t it less fair if the person who previously lucked into being born in the wealthier country gets the job?

My point isn’t to diminish the very real problems facing the US working class. I just don’t see why working class people from Mexico or El Salvador are any less deserving of my sympathy.

Things are the way they are because American laws are made by American lawmakers, elected by the American electorate.

If the rules could being set independently of the interests of the electorate, our rules could become more moral - but it seems to me more likely they would become a lot less moral.

Being born here or there is an act of random chance. The fact that some countries are developed while others aren't is not random chance. Especially in the new world where all countries have had exactly the same amount of time to develop.

What does that have to do with anything?

Doesn't this statement ignore a huge amount of context?

Reading through that thread reminds me why I deleted my Twitter account.
