Bankruptcy or choosing to default on credit card debt. What are the ramifications of each?

Can you answer perkins’s question about Bankruptcy?:

I have A LOT of credit card debt from opening a business and having to sell it in one year because of family responsibilities. Saw a bankruptcy attorney, but the options don’t seem to work for me as there’s no way I could ever pay off these debts.
I know it’s very immoral, but what will actually happen if I just stop paying on them? I know I’ll be inendated with phone calls and lose my good credit standing, but can they attach my bank account or any other asset?
