The large wave of immigration took place in 2015. Integration is more than difficult. Crime rates among immigrants remain high and many lack a perspective.
Today some are desperate to leave and are attempting to return their home countries.
For those who stay in Europe, social problems include prostitution for survival. Greece for example does not have social security networks equivalent to those of Northern Europe. The remains of what was there was terminated in the last financial crisis.
Hopefully this story continues with the rebuilding of the home countries, which in the cases of Syria, Libya and Iraq, have been destroyed by US oil-driven foreign policy under the Bush and Obama administrations.
