OP, you're judging the dating pool by being on a Relationships forum intended for people with relationship problems. You may as well go onto a wedding website or wedding blog and read threads of women madly in love with stories of meeting great men, to get a balanced view.
People who find decent partners don't normally talk about it on the internet. People who don't will, their voice is the loudest. To allow them to colour your judgement before you've even made a go, is a self fulfilling prophecy. Because your energy will put off decent men, attract arseholes and you'll settle for a crap man believing he's better than what you read about on here.
If you think about it logically, in this day and age, a 'decent' man (or woman!) will want to establish his career, buy property, maybe travel the world and enjoy his hobbies - and when he's done all that, he'll want to settle down. This takes you into your 30s, and that's why there is a sizeable pool of men who actively want relationships and prioritise them. It obviously depends where in the country you are, and big cities/towns will have more of these men. Yes, some of these might not want someone with kids, but there will be others who don't mind - particularly those that don't want kids of their own.
So, if you do want to meet someone, get off these boards, be your most positive, real self, go out there and date! Learn to recognise red flags early on, focus on a guy's life choices rather than just the image he portrays, and mostly tell yourself you WILL meet a fantastic man. With that sort of attitude, at least you'll enjoy dating a lot more, and that will come across to the people you meet.
