this is a pretty bias article. There is no reason you should do the math over 10 years. That is basically a random number since presidency is only in 4s. Also it should be noted that 19.6 trillion in 10 years is less than 2 trillion a year, about $6 a person increase but it isn't coming from people. With that increase we get literally free health care (like the rest of the world). Healthcare for me as a healthy individual is closer to $1000 a year than $6 so each person has a lot more money in their pocket. Sanders plan also does not involve any change in income taxes if you make less that 2.5 million too. He also plans to close a lot of loopholes so taxes can't be evade by companies which is great.
