A creditor who extends credit to a consumer to purchase a consumer good under a written security agreement obtains a<u> "purchase money" </u>security interest in the consumer good.

A PMSI is utilized by some commercial lenders and credit card guarantors just as by retailers who offer financing alternatives.

Income is one factor used in determining whether or not a job is middle class, and the other is the nature of the work.
In the United States, 50% of people live in the middle class, according to the most recent Pew Research Center survey from 2021. This is a reflection of the middle class's longer-term downward trend over the previous five decades.
According to a recent Pew research, the majority of Americans were not middle class for the first time since at least the 1960s. 
Just 50% of adult Americans in America lived in middle-class households in 2021, compared to 54% in 2001, 59% in 1981, and 61% in 1971.
Both the middle class's demographic share and its part of the income pie have been declining.
