5) The overall earning potential of the Indians in UK will ensure that property and mortgage market are owned by the Indians.
6) Even though Chinese invest in the UK, the Chinese wont be able to racially and culturally integrate as easily as the Indians ( Proof is in the British Parliament)
If you put all of this together, in the next 20-30 years, atleast 20-30% of all land and wealth in the UK will be owned by Indians and therefore will become an unofficial Indian colony(if you want to call it that way).But it wont be called as such.
