I don't know why I'm bothering but.
It is painfully obvious every thing you say comes from books, pamphlets, etc. My guess is you have little to no lived experience of what you speak of.
I'm particularly interested in your assertion that Laos is Marxist-Leninist. This can only come from a slavish loyalty to what you've read. Of course the LPRP calls itself M-L. But, how can I put this, so fucking what? It means nothing on the ground to most people. Only to those state employees who benefit from the drip from China, and obviously to those minorities the LPRP continue to discriminate against. For the 80% rural population, whose lives the Party barely touches, it means nothing. Collectivisation still means subsistence. Growth, funded by being in hock to China thanks to Belt-and-Road, means poverty. Healthcare is almost non-existent. Education is fundamentally basic and largely carried out in an environment you wouldn't put your dog in.
The LPRP is completely corrupt and nepotistic. 10% of the CC are children of former Presidents or Secretarys-General. 25% of the CC are family related. A new elite has been created to replace the old Royal elite - often literally by mixing (marrying) between them. This is not an overthrow of society. This elite has willingly succumbed to being nothing more than a Chinese satellite and trust me it's fucking depressing to see the white shirts making money off selling the country to China (while fucking up the eco-system for the rest of SE Asia) while the rest of the country remains, literally, painfully thin.
So please do tell me your version of how M-L has beneficially altered the material conditions of the Lao peasantry. Or how it has stopped corruption. Or produced anything other than a new elite.
You know nothing.
