1. First calculate lifetime income: w=100+50/1.1=145.45...
Solve Max U by substituting c2=1.1(w-c1)
Then you have c1*=w/2=72.72... c2*=80, therefore saving=s*=27.27...
2. I think the new system doesn't change anything at all since 10<s*
3. This argument is interesting. I think it's wrong since grandfather's $10
is father's $11 and son's $12.1, Gov needs to increase tax to finance it.
