| In the United States, the biggest
change in spending has been in the amount spent on food, which has decreased
from 46% of the total family budget in 1901 to 19% of present day totals. This
is due to the fact that people are now able to buy more and better foods at
lower prices. As a result of the growth in fast food restaurants (for example,
McDonald’s or KFC), more people are also eating out. Thus about 30% of today’s
food budget goes on meals eaten outside the home while a hundred years ago it
was only 3%. At the beginning of the 20th century, few people owned their homes (only around 19% of working families) or cars (at about ＄ 1,000 per ear this was well above the average family income of ＄ 650 per year), as most people were unable to borrow money. But there was a rapid rise in both home and car ownership during the mid-1900s A. People are eating less. B. Eating habits have changed. C. Fewer people are eating out. D. Foods are less expensive.
