(CNN) - Elizabeth Warren's aggressive plans to level the playing field for the American economy are drawing heavy fire from billionaires, even ones who acknowledge the system needs to be fixed. The chair and CEO of Omega Advisors, who has promised to give away his fortune to charity, even choked up talking about Warren's wealth tax. Warren is hardly the first presidential candidate to rail against the billionaire class and claim the system is rigged. The billionaire backlash stems from apprehension over the extent of Warren's efforts to remake the American economy by raising taxes on the ultra-wealthy. In 1989, the middle class held $7.1 trillion, compared with $4.7 trillion for the top 1%, according to the Fed.
