I do not have a problem with people having money they honestly earned or that is a result of shrewd investment (such as seeing a major silver shortage and investing in the stuff when everyone else thought it was going nowhere, then seeing the shortage hit and becoming extremely wealthy on it). What I do have a big problem with is when they pompously glorify poverty and hardship on everyone else. You have a little extra, you need to throw it away. Even children's ice cream money has to go. And then you yourself are not willing to follow that example.
In recent years, I have seen this trend quite a bit. They wanted people to cut way back on their regular work, and throw away whatever extra money they happened to have. (And shortly after, they were expected to buy expensive computers and electronic devices, which require maintenance--hardware and software). Then it was the ice cream cones. And now, they want people to move out of their houses and rent tiny studio apartments. Even quitting their jobs if they can't attend all the boasting sessions and do all the field circus they are supposed to.
And among this, those at the top, those who are issuing these directives, are getting filthy rich at the expense of the flock. Filthy, not because of how much they are making, but how. They are effectively stealing from the flock, glorifying hardship and misery, and then living first class. Off the money they stole, not off money they made honestly or that is a result of investing wisely. I have a huge problem with that.
However, anyone that quit donating to this scam, you have the right to all the money you honestly made. If you are not the type that pushes hardship as a necessity to serve god, you are fine being rich. (Poverty is a punishment, not a virtue.) You make wise investments--suppose someone used to donate enough money to buy a tub of silver a month, and then uses the money to buy the real silver and donates nothing. Later, when the currency craps out, they have quite an abundance of wealth. Nothing wrong with living first-class under those circumstances.
