Why are so many people addicted to lotteries?

In China there is a phenomenon that many people are addicted to lotteries (the lottery). These people fantasize about becoming a millionaire one day. I do not approve of this behaviour because the probability of winning is very slim (low). Hard work is more effective. Achievement usually comes from your hard work and something that you have to give up sacrifice. For example, if you want to speak English well, you have to spend a lot of time studying and practicing.

Note: I would use "the lottery" instead of "lotteries" because that sounds more natural to me.  But I would be curious to see if other native English speakers agree with me.

I hope this helps!  Good luck!
