Wouldn't you agree that rich people benefit most from the society that everyone has created?
Society and government are two separate things. Why is government entitled to anything because of benefits that society provides?
OK, we've parsed this one before but I'll repeat it.
According to the Lib Doctrine: no one got wealthy on their own. Society made them wealthy. Therefore their money isnt really theirs. It belongs to society. They just happened to be i the right place at the right time. Like winning the lottery.
So government really has a duty to take as much of that wealth as voters want and redistribute it to the people, whose money it is anyway.
Seriously, they actually believe this.
