Evidence for what, exactly?
- Let's take it as a given that you can pay for the trip of the applicant. But being able to pay for the trip is not the only reason why an applicant is asked to provide financial details. They want to gauge if it would be in the self-interest of the applicant to abandon the job in the home country, to overstay and to work in an illegal, low-wage job.
- Plenty of people try to get into Europe to support their family through remittances, so leaving family behind is not evidence of an intention to leave, either.
So the best situation for an applicant is a stable job that pays more than illegal, unskilled or semi-skilled work in the UK. And yes, there is a bit of judgement call by the ECO in the decision, based among many other things on the experience with other applicants from that part of the world.
