“Enough economic resources and opportunities”

This means possessing enough material resources and opportunities to function with a meaningful degree of economic independence.

For example:

Suppose two people are legally free to choose their employment.

Person A:

• owns land;
• has savings;
• can obtain credit;
• can leave an employer;
• can start a business.

Person B:

• owns no land;
• has no capital;
• has little access to credit;
• must immediately find subsistence;
• has very limited employment alternatives.

Both have legal freedom to choose employment.

But B has much less practical economic capacity to exercise that choice.
