Does actually national debt affect a common man's life?

I am US permanent resident & I am planning to settle in US for rest of my life. I am a doctor. I am much impressed by the superiority of US in the world in almost all sector & its my ambition that US remain so forever. Currently US national debt is 83.4% of its GDP & its presumed to raise further....My question is whether this growing debt affect the prosperity & routine life of a common man? As Japan's national debt is 192% of its economy & still its flourishingg. Than whats the importance of debt?
