By DANIEL WAGNER Americans got wealthier for a second straight quarter in the fall, as the economic recovery again boosted home values and investments.The Federal Reserve says net worth - the value of assets such as homes, bank accounts and investments, minus debts like mortgages and credit cards - rose 5 percent from the second quarter to $53.4 trillion.Even with the gain, Americans' net worth remains far below the peak of $65.3 trillion reached before the recession began, underscoring the vast loss of wealth over the past two years.
