Reminder that the money is printed out of thin air and it's not really that we need anyone's stored wealth. Not even liquidating a mansion or ten from a billionaire, or from all billionaires, is going to solve our problems. Sure they are worth a lot to one person, but how much is a mansion worth to society in effect? Not much really.
The system is designed to have poor people. It must so that there is incentive to work. Otherwise we would have to force people to work. I'm not trying to justify the ways things are, I just don't see going after stored wealth as solving the problem especially when it is not their assets we need or their made up currency.
I've also used VoIP.ms. Making and receiving calls is possible but requires setting up a SIP client app on your phone. Getting the settings right can be tricky.
