People moan about it because they and their governments haven't understood the consequences of their votes and actions. They wanted to have their cake and eat it too.

It doesn't help that elections are also just popularity contests and charades of endless lies and empty promises. Your average voter is far too I'll equipped to make informed judgements on complex issues making them easy to influence through fear mongering by groups with vested interests in seeing the results they want.

Everything is fucked.
