People on the Internet, and specifically reddit/Lemmy, sit and read all this negative shit all day, every day, and then come and regurgitate it for others to do the same. Life has literally never been easy, except for a very select few. I personally think some of the best things in life come from the fact that there are difficulties weighing in opposition (winter and summer, as the most general example). If you don't want to have kids, that is great, but to say it's because the world is difficult is just such a copout, because the world has always been and will always be difficult. You need to live for good times, weather the bad times.
