Not all, Nepalese Brahmins these days are poor or very poor. I know of Brahmin families that live on 13K/month in Nepal. They are priests but very poor. Meanwhile, these Nepali US and Aussies Brahmin are ripping off over their due to their high demand. I am skeptical about their competency in the ritual practice as well.

I know someone who is one of the most popular Pandit in the US. He is also involved in inviting or sponsoring big celebrities from Nepal and other of his side job.

That dude "pandit" used to work assisting my grandfather during any kind of ritual here in Nepal. Many of our jajaman invites my grandpa and my grandpa used to take him to carry the "Daann/sidda" as the dude could not even pronounce the mantra properly nor went to any "Bhate Pathsala"  he does not get an invitation from any of our "Jaja man". Now, since he went to the US on a visitor visa also, his son applied for his green card. I bet he earns tonnes of money sharing just based on what he blabbers in the ceremony.
