Reform banking practices to enable qualified homeowners to re-finance their home loans, which will stimulate the economy

Due to no fault of our own, many homeowners have decreased home values and cannot refinance at current lower rates. We bailed out the banks, but their new stricter policies are limiting refinances. We need Obama to step in. Banks will only refinance 80% of the current value. This requires most people to "pay down the loan", which we can't afford. Difficult times require creative action. If a homeowner qualifies for the loan (based on salary, credit rating, etc.), reduce the loan-to-value requirement to 90% or even 100%. Less people will walk away from their homes. And if people could get a 3.5% interest rate (vs. 6.5%), I guarantee that they would feel more comfortable spending money...stimulating the economy. WHY CAN'T THIS BE DONE? Because banks have no initiative to reduce their profits
