If Kerry writes a check for a new car, she is using money as a

Medium of Exchange

Explanation:

Money can be used in different ways such as being a medium of exchange, a store of value and unit of account. The relevant use here is as a Medium of exchange.

At some point in history, humans used the barter system to trade which means that they exchanged goods for other goods. This was a inefficient because it could be quite bothersome deciding how much of one good to exchange for another.

Money changed all that because it was able to value goods relatively and therefore be used as a medium of exchange for goods. In writing a cheque to purchase a car, Kerry is using exchanging money for the car making it a medium of exchange.

the reason the welfare system causes so much of a burden on its recipients is because the welfare system does not give its recipients any real tools to actually get out of poverty. the welfare system has embedded poverty deeper into society and has made it harder and harder for people to escape poverty.

in other words, it stoped the poor, and now its making it worse.
