I think the answer is free market
Subsistence crops are plants which are grown by farmers for themselves and their family, leaving little or nothing to be marketed for money. (ex. rice, corn, and milk.)
Subsistence farming is a farming system in which farmers focus on growing enough food to feed themselves and their family.
A Lobbyist tried to persuade politicians to vote a certain way on certain bills that would benefit the lobbying firm that he'she works for. For example, a Lobbyist from the American Association of Retired Persons would try to convince politicians to vote to benefit people who are retired.
Good luck :)
