[单项选择]Many Americans-perhaps most of them-aren’t ready for President Bush’s "ownership society". The idea sounds good. Employees could shift a portion of what they pay into Social Security and put it into individual accounts that might gain higher returns in, say, the stock market.
They could also reduce their tax bill by starting Health Savings Accounts, Retirement Savings Accounts, and Lifetime Savings Accounts.
These options reflect a certain conservative logic. Rather than having the government or your company decide how much retirement money or healthcare you get, you can decide for yourself.
"If you own something, you have a vital stake in the future of our country," Mr. Bush explains.
"The more ownership there is in America, the more vitality there is in America."
The flaw in this logic is Americans lack of financial sophistication. For example: Less than one-quarter of working-age people characterize themselves as "knowledgeable investors," accordi

[单项选择] One day in my class, Maria shared her feelings about money, "Money worries me. I think I want to live without money because I hate it. I HATE MONEY." We were all touched by Maria’’s words as they reminded us of the spiritual burdens that money managing can bring to us. After class I offered to help Maria deal with her financial problems. She hesitated to accept my offer, and I could see from the expression on her face that she was afraid of what it might involve. I quickly assured her that I wouldn’’t make her do more than she was able to. I told her frankly that I didn’’t enjoy managing my money any more than she did hers and wouldn’’t burden her with guilt, judgments, or impossible tasks. All I would ask her to do was to let me help her look at her fears and try to make some sense of them.
Maria still resisted my offer, and I can remember the excuses she gave me as they were the repeated complaints I had heard from so many people. "I’’ll never understand money," she said. "M
