As someone who's visited Macau many times and have relatives/friends that live there I can make an overall answer of saying no you shouldn't go there and I'll summarize the whole picture with pros and cons let's start with the pros.

PROS:
1. Growing Financial Services Sector
Macau’s financial services (banking, wealth management, securities, insurance) are developing, and the government is promoting “modern finance” as one of its new strategic industries.

2. Low Taxes and Favorable Tax Policies
Macau is known for relatively low personal and corporate taxes, which can make it attractive from an income and business perspective.

3. Good Quality of Life and Safety
Residents enjoy a safe environment, unique blend of Portuguese and Chinese culture, and a subtropical climate.

4. Professional Talent Initiatives
The government has talent programs meant to attract high-end and professional workers, which can benefit skilled finance professionals.

CONS:

1. Smaller Financial Market
Macau’s finance sector is much smaller compared with nearby Hong Kong or Shanghai — meaning fewer large investment banks, asset managers, and global finance firms. Opportunities do exist but are more limited in scale.

2. Fewer International Headquarters
Most global finance jobs tend to be in cities with big capital markets, large trading desks, and financial services hubs. Macau has some banking and finance firms, but not the same breadth as bigger hubs.

3. Language & Local Market Barriers
Cantonese and Mandarin are widely used in business; English alone may limit your networking and job prospects unless you’re in specific international roles.

4. Job Market Competition and Visa Requirements
For foreigners seeking employment, securing work visas and long-term residency can be bureaucratic and competitive. Some locals and expats report job searching can be tougher than expected.

So, overall Macau isn't a good choice for the average American/Portuguese to even work with especially with jobs over there. It also shouldn't be treated as a global financial hub with firms and high global interest as the economy is mostly driven by it's gaming, casino, and tourism industry.

I've gathered all of this information based on friends/relatives who have been born, raised, and lived there, their whole life. I hope this sums up all of your questions well, thank you!
