Financial circumstances; home life

Nikita comes from a country with a relatively low average income, therefore Nikita's subjective well-being is especially likely to be influenced by satisfaction with her FINANCIAL CIRCUMSTANCES. This is because she earns a low income which is likely to be a challenge in her new location, financial circumstances would influence her lifestyle, so she has to be extremely economical.
Meanwhile, Francoise lives in a country, where the standard of living is fairly high. Francoise's subjective well-being is especially likely to be influenced by satisfaction with her HOME LIFE. Francoise is more financially stable, so she doesn't need to be so economical with her spending, her well being is based on her home life.
