I've been studying socio-economic impact of federal budget deficits and growing national debt. Can you help me with these two questions that I am having a problem with?

1. What is the likely impact of large and growing national debt on investment by private firms? Can you show with a diagram illustrating the effects of budget deficits in the loanable funds market. Please label the diagram and show any shift of the curves.
2. Explain the likely impact of large and growing national debt on the future generations of a debtor nation. Include and explain the "inter-generational income transfer" and the "inter-country income transfer" issues in your responses.
