Honestly, as someone living abroad, there is not much to do if you're not a highly ambitious person who really cares. I commend you for feeling some responsibility because I fear most later generation immigrants don't.

I am going to get downvoted for this, and I am also adding to your feeling of doom here because I feel as hopeless as you, but I believe there is some truth in this quote in every society, "Every nation/democracy gets the leaders it deserves".

Young people barely vote, so old people with their traditional outdated beliefs continue to put these corrupt assholes in power, so they deserve the corruption they bring and befalls them.

There is also general corruption in society, which I have personal experience of. My grandparents easily accepts bribes when voting during elections because they think, "why bother, how is my vote going to change anything? I need this money anyway.". Corruption is rampant and extends to every institution. My parents had to bribe the hospital, so they would do a better job when I was born through caesarean section during a time when infant death was relatively high. My uncle is a police officer and accepts bribes too.

I know this is a lot more complex issue than I am describing, so take everything I say with a grain of salt. This is just my way of understanding all of this, which may very well be wrong. It is sad to see that people are only beginning to stand up now when corruption has been going on for ages.
