This would be a GOVERNMENT health care system. In other words, the main source of funding is tax payer money, so that would mean employers, along with everybody else, would have to put a substantial amount of money in (even more than most people). Even though they still need to pay their employees, due to keeping the health care system going, wages would be down as a result because about half, or more than half (or whatever the case might be), of the money being brought in for the business and the employer is being pulled into the single payer insurance. It affect productivity because employers may have to either lay off workers, make some of them part time, and/or, due to the cost, the product that they normally produce would be hard to get in.
Crazy Bernie said that this would cost $32,000,000,000,000 (trillion). Employers would have a heck of a time paying their employees, provide health care, and stay in business. If Crazy Bernie had his way, businesses across the nation would go out. Trust me when say, Crazy Bernie, and others in the government, will NOT reach into their own pockets to pay for this. Even if they did, the combined income with everyone in this nation, couldn't even begin to scratch the surface of having this paid. We're $20 trillion in debt, so Crazy Bernie would live up to his name if we went through with this.
In conclusion, this affects ALL taxpayers, not just a select few. The most terrible thing behind this is, everything that I mentioned doesn't even include gas, water, electric, school, property, car, phone, credit card, food, meds, and whatever else as far as bills for plans and taxes for products. We don't have the money, but people like Crazy Bernie don't care.
