The WTS is a former publishing house that is currently selling its assets to survive. That can’t last forever. Plus lawsuits, plus growth in poor countries and decline in rich countries, and so on... it is in a far worse position than other churches.
And as a matter of fact the Catholic Apostolic Church collapsed despite being rich because of its end time doctrine. It still has assets but no members.
It is simply a non-sequitur to say that because JWs haven’t collapsed in the past therefore they won’t collapse in the future. Or that because it had the resources to survive in 1925 that it will have the resources to survive the current crisis. These are bad logical errors.
