Most women i know date local and marry abroad - weird trend

Hey y'all,
background : IT/startup

working in same company from many years and i see a trend. almost all my coworkers i knew are posting stories about their wedding life in different countries. dubai,aus,us,eur almost 10+ women i knew dated people in India but as they approach hitting the wall they quickly catch a person who is working in developed country(never a developing one) either via love or arranged setup.

it has a lot of benefits:
1. far away from exes - cover up the past!
2. lifestyle upgrade with minimal/no efforts - piggyback on the visa guy
3. don't want to stay with in-laws
