4.500€ is about the starting salary of an executive director in the Anglican Church in Canada. I imagine the archbishop get more. In the old day's in free Estonia, the pastor was accorded with the same respect as a high school principal and paid the same as the principal. How much does a high school principal get paid these days?
So, what's the problem?

The EELK leadership - communists, freemasons and crypto-Catholics - only use Christianity and their own organization as a vehicle to pursue their own financial goals. There is nothing Christian about EELK, as Toronto St. Peter's members have found out, when holy communion was weaponized to reduce the number of older congregants.
