I completely agree with your article and can see this will continue for the next 5 - 10 years atleast due to the massive immigration influx and the changes in UK's social trends giving the rise of single tenants.
In truth, government is turning a blind eye to immigration. They need the productive taxpaying population in order for the Chancellor to balance the books. The percentage of existing UK citizens who are retiring is increasing. The governments finacial models, predicting future social & financial trends, showed that unless governments took action for the split of taxpaying population to remain at approx. 66% productive, 33% retired or on unemployment benefits, then by 2050 the predicted trends would become a reality with the split in population to be completely reversed, 33% productive, 66% retired! Hence the reason why government is turning a blind eye to an immigration influx, otherwise if stopped, then where would be the productive taxpaying population be to stop this reverse from happening.
