You wish death for Bangladeshis - just like Modi??
Treatment in Bangkok is not that expensive, most people are going there now. Treatment in Bangkok is cheaper (and more advanced) than Bangladesh and India in some cases. India is way cheaper than both, but visa is the issue.
However the Specialty Medical Services sector in Bangladesh is changing rapidly, to cover the $5 Billion spent overseas by Bangladeshis annually. India is losing this $5 Billion now that they've curbed most medical visas for Bangladeshis, which is now going to Bangkok, Turkey and Singapore.
