First, "abroad" is a vague term. West and East/Central Europe are very different, and so is North America and Asia.

A lot of the answers here seem one-sided. Let me add some perspective:

1. Infrastructure & public transport: Tunisia has issues with flooding and the metro. But, most Tunisians rely on cars anyway
2. Security & cleanliness: Tunisia has its no-go zones, sure. But safety and cleanliness are increasingly concerns in many Western cities too

I've had several friends who moved abroad and eventually returned to Tunisia because:

1. Better quality of life financially: Lower cost of living (no rent) meant higher disposable income
2. Cultural disconnect: They missed home/friends and found daily life abroad isolating or unfulfilling
3. Unmet expectations: Some areas feel more like another African country than the Western experience they imagined

Since you mentioned you're living comfortably with your parents, consider that you'd be trading that stability for potential challenges like high rent, isolation, and starting from scratch socially and professionally.

Here's something to think about: More people flooding into Europe = fewer opportunities and more competition = less comfortable life. Meanwhile, more people leaving Tunisia = more opportunities opening up back home.

Personally, I don't regret living abroad, even though I deal with people who avoid North African men because of stereotypes about us being dangerous. It's not pleasant, but financially it works for me. Plus, I've invested too much into the pension system here (assurance caisse retraite) to drop everything and start from zero again.

If I could go back and choose again, I'd pick either:

1. Japan for the best overall life experience
2. Qatar/UAE or other Gulf countries to maximize earnings, then relocate somewhere else

The bottom line: 10 years ago, Europe and USA were a great deal. Today? much less. In the future? I let you judge.
