I certainly see (and partially agree) with your point and I am by no means defender of the banking institution …
If someone walks away from a loan , do you think he would be screwing the bank ? I do not think that he will be like Robin Hood , stealing from the rich and giving to the poor!
Either the government will pick the loss (all of us) or small bank investors (think 401Ks or other retirement funds)
In a nutshell , he will be screwing his fellow man !
Now , do I say make good on your loan at the expense of your children going hungry , hell NO, BUT I say that you should live a couple of years under your means and pay us much as you can !
If we agree that the society is footing his bill then it would only make sense to tap that common resource only if you have to and not to just preserve your way of life!
