One medical emergency and your credit will be ruined. Wait a seven years without contracting the debt collector and the debt becomes uncollectible. After three years roughly three quarters of the effect on your credit will evaporate. That's what actually happens beyond the hyperbolic political grandstanding.
Remember kids, if you get a bill that you can't possibly pay. Don't pay it. Let it go to collections and pay it for pennies on the dollar (another trick, tell them the most you can pay is $10 a month or something else low. Pay off that debt in 2075) or just wait for it to become uncollectible.
