I have been an AMEX customer since 2010. From Zync up to now Platinum. These cards can be financial tools. But be aware, AMEX may take away your financial tools and freedom whenever they see fit. This has been my experience:
In 2021, in my 2nd year of law school, AMEX rewarded me by lowering my preset spending limit.
In 2023, after graduating law school, AMEX congratulated me by further lowering my preset spending limit.
In 2024, after finally securing my dream job, AMEX again further lowered my preset spending limit (amidst heavy law school debts).
If you have the American Dream of pulling yourself up by your bootstraps, I commend you. Persever in your passions. You will likely need help accomplishing your dreams. And if nearly 15 years of being an AMEX customer has taught me anything, it has been not to rely on AMEX to help accomplish my American dream.
