With all the conspiracy theories we hear about George Soros, can anyone explain to me what benefit a borderless world would be to George Soros?

Soros made his fortune on international unrest. He plays/played the currency markets and makes money when currencies go up or down. Unrest always creates havoc with currencies and he profits from the fluctuations.

He is less a liberal "do-gooder" than an opportunist who discovered he can sow the seeds of unrest that he profits from.
