The term "plowing back into" refers to putting resources, money or profits back into a business or project to foster growth and development. However, if one wishes to express the opposite of this action, several antonyms may come to mind. For instance, words like "disinvesting," "withdrawing," or "divesting" describe the process of taking away resources or shares from a company rather than investing more in it. Additionally, words like "shrinking," "reducing," or "downsizing" describe the process of decreasing a company's resources or activity. In essence, while "plowing back into" evokes growth and progress, its antonyms portray a different picture of reducing, cutting back or divesting.
