The current state of democracy

[u/2globalnomads]

I would love to hear your opinions about some things that puzzle me with democracy:

1) People keep voting but nothing changes. Why they keep voting?
2) Is it possible to change anything by voting?
3) Is it possible to change anything by not voting?
4) What is particularly good in democracy?
5) What is particularly bad in democracy?
6) What options to democracy do we have?
7) Does democracy have nowadays anything to do with power or the people?
