Answer:
False
Step-by-step explanation:
It isn't clear what the statement is referring to, which is reason enough to consider it False. "Los Angeles County" in this context could refer to the county government, or to the business and industry within the county borders. Either way, $1 trillion is an overestimate of the revenue involved.
The county of Los Angeles has a budget of about $40 B, considerably less than $1 trillion. Business and industry in the county generate a gross domestic product of about $700 B, also somewhat less than $1 trillion.
The statement is False.
