Half of the information here is true.

1. Yeah I can somewhat agree they are hospitable.

2. "Every worker can earn a good salary without being taxed on income." (Good Salary) I'm earning less in this country and this is coming from a (white collar worker). So if they'll add tax to a meager salary, then nothing will be left.

3. Safest (just don't include the roads and it's definitely safe except for Asians)

4. Modern and Lavish (some parts, yes). If the word lavish is being used, I think of DXB.

5. Don't have a health card so yeah, I don't have any idea about this HealthCare system here.

All in all, Qatar is still a good place to work.
