Donald Trump: 25,000 people show up at my rallies because of one major issue

Trump: Political system rigged

Presumptive GOP presidential nominee Donald Trump told CNBC on Thursday that wage stagnation is the reason 25,000 people show up at his rallies.

The middle class has been "absolutely forgotten," while the wealthy have done very well, the billionaire businessman told CNBC's "Squawk Box" in a phone interview.

"The middle class, many of them haven't had an effective wage increase in 20 years," Trump said. "They're being taxed at a much higher rate. And they're working much harder. It's supposed to be opposite."
