"They [immigrants] have few costs and many are willing to sleep on floors to save money."
"Denham [John Denham, MP] says the arrival of 14,000 Poles in Southampton has cut rates for building workers by half."
"London, where migration is greatest, also has the highest unemployment, especially among British-born ethnic minorities."
"Poor families in this most expensive city can't pay for childcare, and compete for jobs with single migrants willing to take less than a living wage. But the rich prosper: restaurants, cleaners and all other services are cheaper because wages are low."
There's lots more like that. Furthermore, she is mostly talking about legal immigration. Since illegals are often willing (or forced) to accept below minimum wage, they make the problem even worse.
As Toynbee says, mass immigration benefits the pampered, middle class but is a disaster for the low-skilled and poorly educated.
