I know you've said you're not willing to discuss publicly how you've managed to work so hard for so long and achieve so little, and it's not my intent to pick on you, but I think it's important to point out that the way your life has turned out is, barring any more details from you, a textbook example of not making something happen as you must under an unfair system and ultimately something you will have to live with, rather than some kind of inevitable fate for all men nowadays.
I think we're about the same age, and I worked like you say you do sometimes when I was young. In my 20s and 30s I mostly focused on working hard, saving enough money to take long periods of several months off, and then going to Europe or Latin America to enjoy life. I like languages, so I learned several, mainly for the fun and intellectual satisfaction of it. I've had some very difficult times in my life, but overall I look back on it all with a sense of joy and wonder, and I've very thankful for it. In addition to the exciting and enjoyable life I had as young man, now that I'm middle aged I have an angel of a wife, kids who I adore, and a modest but comfortable life. Like I said, it's not at all my intent to pick on you, but I think your suggesting that achieving what I have is unlikely is very harmful and I wish you'd frame it as a personal failure, rather than something that will inevitably happen to any young man nowadays.
Look at Daniel H, for example. He just posted about how things are hard for a guy his age in his situation, but he still got married and it trying to make something happen. There are no guarantees, but I'd imagine he will achieve a family and a generally happy life. Seek and ye shall find, like Jesus says.
