Incorrect. ICE is built off the background of 30-50 years of propaganda against "immigrants", most of it completely untrue.
The same is done for "benefits scroungers", despite the evidence being that welfare fraud only accounts for approximately 1-5% of the cost of administering state welfare, and state welfare would be about 50%+ cheaper to administer if it was a UBI rather than being means-tested. In fact, much of the measures that are implemented with the excuse of "we need to stop benefits scroungers", such as testing if someone is disabled enough to work or not, etc. are simulatenously ineffective and make up most of the cost.
Nevertheless, "benefits scroungers" has entered the zeitgeist in the UK (and the US) because of this propaganda.
The same is true for propaganda against people who have migrated to the UK/US. Many have done so as asylum seekers under horrifying circumstances, and many die in the journey. However, instead of empathy, the media greets them with distaste and horror — dehumanising them in a fundamentally racist way, specifically so that a movement that grants them rights as a workforce never takes off, so that companies can employ them for zero-hour contracts to do work in conditions that are subhuman, and pay them substantially less than minimum wage (It's incredibly beneficial for the economy, unfortunately).
