Laos is poor today and Poor will be poor tomorrow.
That is the fact because Lao leaders are lazy and
corrupt and not highly educated and sold the Lao people
out long time ago.Lao leader have been betraying Lao people ,
they don't care about Lao people but their families and their
political party.Laos and Thailand are the same which rule
by the dictators.
This hasn't happened yet. So your opinion is just a guess. But don't get me wrong, it is a reasonable one. But I believe Laos will not remain 100% as poor as today. They might benefit from economical unification although slowly. But we shall see.
