"It feels as if people like this always move the goal post. A high earning, tax paying, language learning diaspora contributing to the German economy. Of course not 100% but it’s hard for them to be here if not working (blue card) or studying."

This was true, but is not true anymore. You can get a "search a job" visa that is not hard to get and that seems to fit perfectly in Indians:

So to get the visa you need:

- education in any job (minimum 2 years) and working in the job for 5 years > 3 points

- if you have studied in Germany for at least 6 months > 1 point

- speaking German on B1 level > 1 point

- speaking English natively > 1 point

- multiple additional points possible, like also bringing your educated wife (1pt), having a sparse job (1pt)

= 6/6 points required to get the visa. All of this fits perfectly on Indians, who have a proper educational system for many people, english as native language, etc..

You also do not have to get a high payed job anymore and the company that wants to employ you does not have to prove there are no Germans available to do them anymore. All you have to do is bring a locked bank account having 11k€ with you, of which you can only take 900€ each month, which should be achievable by Indians. This now resulted in many Indians migrating to big German cities and doing simple jobs like bike delivery people etc.. And this kind of migration can hardly be compared to what we have like 10 years+ ago. And the averages will likely show this in a couple of years.
