I'm not calling you racist at all, I just don't understand your position as a migrant, independently if you are in Germany or the UK.
Migration is essential if we want to continue to have a minimum of services in countries where the population is almost 0. Europe and the UK population are getting old and the pressure on health and pensions will increase. Without migration to pay taxes, the whole system will collapse in less than 20 years.
Germany was accused a few years ago, during the Afghan/Syrian war, of opening their borders to a massive influx of refugees to the EU. Merkel did it for clear economic reasons (she was not doing it because her heart was overflowing with sympathy) her government wanted to get new tax payers in their country, and her gamble paid off.
To quote ..."More than 10,000 people who arrived in Germany as refugees since 2015 have mastered the language sufficiently to enrol at a German university. More than half of those who came are in work and pay taxes. Among refugee children and teenagers, more than 80% say they have a strong sense of belonging to their German schools and feel liked by their peers."
While migrant seem to be a dirty word in conservative press, the reality is exactly the opposite.
