I think there is nothing wrong in doing something that gives you pleasure but doesn't affect negatively your life. I don't think it's wasting live if I often drink, go parties, gamble and etc, it doesn't ruin my life because I am going pretty well.
But I would ask your question with different meaning. What are most of the population wasting their lives on? Answer is simple: making some people rich. Yeah, let's take countries where people work like slaves to feed themselves while business owners are becoming and becoming rich, none amount of money can feed them. They collect money and that's all, they have so much money that they don't even need and even if they invest in something, for example in startups, they do it in order to increase their budget and their budget increases from our pockets, so money in our pockets decreases but for all of this, we work days and nights. That's a problem, huge problem.
This is how our economic system works.If we want to get richer then we need to be smarter and first step is stop doing jobs which keeps you as slave.
Try to do the investments and avoid paying taxes legally which is the way to become richer and Warren Buffet proved it as well.
