As for self-development, I agree with you that men tend to be unwilling to learn a lot of the time. But from what I've seen from women, they also don't really want to learn. It's how people are.
Tinder is, for the most part, heavily reliant on first impressions with regard to looks. If you are a man and you are seeking women on Tinder, you better have your shit together when it comes to that, or you're not going to get anywhere.
This means high-quality photos, clothes, haircut and so on. I'm not saying this is a lot, because dating can be expensive anyway. It's more so that men are not really encouraged to invest in their looks and wardrobe as much as women are.
If you're getting matches and you're not converting them to dates, well, that's another thing entirely.
If you are unable to take it a step further than the dating, it's not Tinders fault.
My wife is a dating coach, and it always amazes her (and me) how unwilling men are to learn and improve themselves. It is not working for them, yet they don't accept advice that could drastically improve their chances. Women are way different in this.
And yes, my wife and I met on Tinder ;).
