Reaching a higher level of education is therefore the best way to obtain higher pay. Current trends in the German education system indicate that an increasing number of young people will acquire a university degree and fewer will finish their education without obtaining a vocational qualification. Intergenerational educational mobility also points to a higher level of training. 29.1 per cent of 35- to 44-year-olds have surpassed their father’s level of education and 40.4 per cent their mother’s. By contrast, only 21.6 per cent of this age group have underachieved in comparison with their father and only 11.3 per cent relative to their mother. However, migration has a considerable influence on how education levels develop. The current influx of refugees is bringing into the country relatively large numbers of low–skilled workers. This means that skills levels in the German population are unlikely to improve as much as current trends in the education system would suggest. As a result, the proportion of the population with a lower income may well rise in the next few years.
