How to enable and perform a soft invasion 101:
>Start with a small town.
>Import migrants.
>Migrants drive up competition by opening ethnically insular low skilled businesses.
>Repeat until your streets are overrun with takeaway Indian and kebab shops.
>Business competition and rapid changes in local demographics incentivise selling whilst making local business owners feel like foreigners.
>Foreign business owners begin to work with newly arrived owners of similar ethnicities.
>Foreign businesses owners then give a tip to their family to make on offer to locally born native business owner.
>Due to limited competition/risk, foreign business owners offer more than is appropriate.
>Rising competition, a fragile community, and an increasing foreign diaspora forces native born owner to accept.
>Rinse and repeat.
Congratulations, you have just performed a soft invasion!
The remaining locals are now homeless, destitute, and without children!!!
Bonus tip: Start in the inner city suburbs and then spread out rural to maintain family support network.
