[简答题] It seems like Americans use credit cards for everything. It’’s a lot easier to spend money that you don’’t see, isn’’t it Many Americans spend money that isn’’t even there — and get deeper and deeper in debt. Why do so many people spend more than they have "Buy now, pay later" has become an American way of life. Recently, American households spent nearly 11 billion dollars more than they earned, creating negative saving rate.
