Restating the article: The top 1% of individual taxpayers in CA account for more than 50% of the state's revenue. It's also worth noting that the top 1% is also very mobile and can move to another state quite easily. CA needs to broaden the tax base and reduce spending so that this volatility can be contained.

It is important to be accurate in summarizing an article. The article states that the top 1 percent of income earners pay *nearly half* (not "more than 50%") of all *personal income taxes* (not "state revenue").

Moreover, you suggest that the top 1 percent of income earners in California are highly mobile and can easily move to another state. While some individuals in this income bracket may have the means to relocate, it is important to consider the broader context. Many factors influence an individual's decision to move, including personal and professional ties, quality of life, and business opportunities. The mobility of the top 1 percent may not be as significant as implied.

Any proposed changes to the tax base or spending should be approached with care to maintain a fair and sustainable fiscal framework.
