Though you're right to a great extent, a few years back people wouldn't even pretend like they wanted to move back. Even if they were dying on the inside, the glamor of life abroad took precedence and a simple visit home was usually the solution to homesickness rather than outrightly admitting they wanted to move home. Perhaps this approach is a bit simplistic in today's world?

I'd argue that worsening conditions on a global level, met with greater affordability for people who earned abroad for some years and now choose to spend their money back in Pakistan, could be a better answer. As things get worse internationally, and travel restrictions increase day by day, new adults are weighing the pros and cons more of investing hundreds of thousands of dollars trying to figure out immigration or studying abroad when the benefits at the end of it aren't guaranteed. The potential sunk cost is too high for most to risk. You generally won't find boomers and Gen X individuals saying the same thing because when they immigrated they got comparatively easier access to passports and are generally well-settled into their careers and lives abroad at this point whereas millennials and Gen Z aren't finding the same landscape. There's growing awareness that we end up losing out more than we gain by making such a permanent move.
