You seem to think that bankruptcy is a constitutional right to a "do-over".
Never mind that it was bad moneymanagement that got you there, people have a right to wash their hands of the debt they incurred.
You see no problem with people not living within their menas, so they are somehow then entitled to have someone else bail them out?
It's not a "constitutional" right to a do-over, but it is a right to a fresh start (which often appears like a do-over) granted by the United States Bankruptcy Code.
Of course there is a problem with people living beyond their means. Of course bad money management is bad! Regardless, our bankruptcy system has to protect everybody if it is going to be objective and not completely arbitrary or subjective. I would rather have a set of laws that I knew would protect me if I needed them (and accept the fact that there will always be some people who abuse those laws), than be subject to a set of laws that either use arbitrary cutoffs and tables or that use a judge's "good judgment" to give me relief.
The inevitable bad apples are the tradeoff for an objective, comprehensive system that applies to everybody.
