Don't left, please. I understand you are tired but your opinion is very useful to avoid repeating the mistakes of the past. That said, please don't just focus on "communism". And think that can also be change without violent revolution. Step by step, dismantling all the negative things of capitalism until reach another "-ism". Call it "supra-capitalism" if you want. All possibilities are open.
As Nick asked: Do you have any ideas to solve or improve the common issues that capitalism is causing, even if that does not involve a complete restructuring of the economic system?
I'm not kidding. You seem a clever person. I'm really interested in your opinion.
