Americans earning six-figure salaries are quietly drowning in debt, and it's bad news for anyone who thought a corporate career was a safe bet.

• Taxes, 401(k) contributions, mortgages, car loans, student debt, and childcare costs eat up a $20,000-a-month salary down to almost nothing, leaving little or no savings each month.
• High earners pay the highest tax rates of any group because their income comes from a paycheck, while the ultra-rich pay far less by holding wealth in investments and property instead of wages.
• Around 10 million high-earning professionals in the U.S. now live paycheck to paycheck, with many relying on credit cards just to get by.
• Housing is a bigger trap than ever since mortgage rates and home prices have both climbed, pushing some young professionals to live with their parents.
• Younger workers are starting to doubt the traditional path of college and corporate climbing is still worth it, which could hurt the broader economy since consumer spending relies on more than just the very rich.

Outlook: Expect growing frustration and burnout among high earners, with more young people questioning whether the traditional career path still pays off.
