It is a common misconception among those who have not looked at Sanders' plan that he wants to burden taxpayers the cost of college tuition. "The cost of this $75 billion a year plan is fully paid for by imposing a tax of a fraction of a percent on Wall Street speculators who nearly destroyed the economy seven years ago. " I am assuming you are not a Wall Street speculator.
As far as taxpayers funding healthcare, who funds healthcare now? If business offers it as a benefit, it is less money for salaries. When people are bankrupt by a healthcare emergency, hospitals take a loss on money not paid. This raises the cost for other patients to compensate.
What Sanders would do is eliminate the insurance companies that are noting more than a for profit betting scheme. They bet they will take in more than they pay out. The difference is their profit. 
His plans are all laid out on the 'net. https://berniesanders.com/issues/
