And yet,
studies show that
19 million UK citizens fell below the poverty line for at least one year out of three, and nearly 8% were in permanent poverty.
Muslims only make up around 4% of the UK population, so even if every single Muslim was in permanent poverty, they would still only constitute arounh half of the population in permanent poverty. Therefore, if your argument is sound, we should be experiencing a level of violent extremism from Christians, Hindus, Sikhs, Jews, atheists, etc, approximately the same as that we experience from Muslims.
But we don't.
And the level of property ownership is 48% amongst Muslims and 64% amongst the general population, so clearly no endimic poverty - especially given the shorter period of time available for the acquisition of property by Muslim families compared to families with many generations of residence.
So the data again refutes your argument.
