The big problem is envy and jealousy over wealth disparities, not the disparities themselves. Encouraging globalist/socialist thought makes the problem worse, whether the disparities get bigger or smaller. The solution is to stop pretending that the forcible redistribution of wealth is virtuous or even ethical.
If Branson doesn't like being a billionaire, he can pay for 250 miles of border wall and help Make America Great Again, or he can do whatever he thinks would be best. What he cannot do is take money from others to redistribute and pretend that is anything other than wallowing in envy and fake generosity (using other people's money to pretend to be generous is as fake as it gets).
Exactly, the rich Libs always want others to pay for their causes. ‘After all I’m giving my time to the cause!’
