Issue is you’re meant to be in my opinion. Its a mans world, the men of the past built everything, it was a good thing.
However, just as women of today have been taught to hate their previous role of serving their husband and motherhood, men are being taught to hate their role of providing and protecting… thus.. the average man is depressed along with various 40+ women who woke up and realised they long for a child and cant have any.
Realtionships are pointless, everything you do with your partner you could be doing while single, theres no family unit, no balance.
Women can adapt to this better than men because men arent physically desirable (to 70% of women). The things that attract 70% of women have been claimed to be height, strength, and in various women Caucasian men as they represent success around certain areas of the world (all things men cannot change) Just as youth and beauty attract men as it represents fertility. So obviously somewhere instinctually maybe? a vast majority of us want our gender roles back.
Not to pile on you or anything, but I'm going to have to disagree.
The men of the past may have built a lot, but don't forget, they destroyed a lot too. In many ways, you could say we're still cleaning up their messes, and having to backtrack to do this, slows down the pace that we could be moving forward.
I don't think men are meant to be protectors or providers, and I also don't think women were meant to be sex dolls or baby-making machines. I don't think we're meant to be anything. That's not to say that I think we're meant to be
nothing - I mean that I always thought we were free to be however we wanted to be. I always thought that was the point of the modern, technological world - that it gave us more freedom to be any way we wanted, as long as we weren't hurting anyone. In the bad old days, before modern technology, for most people life was survival - the purpose of life was predetermined for you, dictated to you. But I thought science, technology, civilization/morality/the rule of law, learning from history, and more compassionate, understanding, modern ways of thinking set us free. I thought people had to be hard when the world was harder, but now it wasn't because we evolved out of it, and now we could do what we wanted with our lives. I thought our lives were open-ended, and our roles were for us to decide instead of being predetermined. I don't think there is, or necessarily has to be, any such thing as "human nature". I think that's the thing about being sentient - you're free to decide what your nature is, yourself.
Someone might say that I'm childish, and therefore at fault and deserving to be mocked, for still wanting to collect and play with the toys of my youth, at my age.
But I say that because we live in the modern, technological, and forward-minded world, I'm free to do that if I want, because who am I hurting?
Sure, in the past, that wouldn't have been feasible when you had to sleep with one eye open in case your neighbor would try to slit your throat in the middle of the night and steal your shiny rocks.
But I say that due to the modern world, I'm free in ways that ancient people could never imagine.
And that's the point of why we built the modern world - to live a more comfortable, luxurious, and happier life where we could choose what to make our lives about instead of being forced to make our lives about mere survival.
I think the problem is, instinct runs deep, and technology improves and tames the world faster than our instincts change to match living in a safer, softer world. Instinctively we still want the same things we wanted since the dawn of our species, even though for most people, we aren't living in the kind of world anymore, that our instincts evolved for.
Growing up I didn't see myself as a "protector/provider". I didn't even know about that stuff at all. I saw myself as just a person, like any other. I liked the interests I liked naturally, acted the way I acted naturally, thought, felt, and saw things the way I thought, felt, and saw things naturally. I thought I could just be, just live. I didn't know I was supposed to live in any certain way. I didn't know I was supposed to fit myself in to a fixed role, and even if I had, I probably would have felt that I wasn't dealt the genetic cards to play it anyway. I guess that influenced my thinking - I always knew I couldn't fit into the jocks/"hot girls"/"popular" world, that seemed to be based on predetermination, being born with the right genetics to be that kind of person. It didn't make any sense to me, to try to fit myself in to a way of doing things where I'd always be on the bottom, playing by their rules I'd always lose, I'd always get nowhere. So I figured, maybe things don't have to be any particular way, maybe you can just make your life about what you want it to be about, maybe you can just be. Maybe I was mistaken. I don't know.
And anything that's based on genetics, where you have to just be born as the right kind of person otherwise you're inherently "lesser", just seems kinda Nazi to me, and again, growing up I was taught those were the bad guys. I don't see how that kind of thinking can ever be the side that's good and right. Growing up in America I always heard a lot about freedom and equality, so maybe it's my American-ness showing, but I always felt that the side that said that some people were inherently "better" than others, was the bad side, the wrong side - stuff like eugenics, slavery, or rigidly hierarchical societies like those in third world countries, were considered morally wrong, and that our society was more advanced and provided a better quality of life, because we grew out of doing those things.
Also I don't think relationships are pointless, outside of raising kids. I think that's kind of a utilitarian way of looking at it. I think relationships are a different dynamic - closeness, like friendship or family, but with its own twist. I think it all has a purpose, and it's all different experiences that make your life complete.
I guess I grew up with a very different way of seeing things. Sometimes I have to remind myself that not everyone sees things my way.
Maybe that's why? Because I just handle it? 
According to this, 50 Cents means as far out of tune as possible.
