Thank you. Developers who jump because they'd rather build from scratch instead of helping maintain and improve an existing solution is irritating. More power

Thank you. Developers who jump because they'd rather build from scratch instead of helping maintain and improve an existing solution is irritating. More power to them, but I respect developers a lot more who stay, fight through legacy code battles, make steps/headway to shift the application to a newer platform that makes practical sense than those who leave. If your employer refuses to move to a stack you feel is justifiably better, in both business and technical aspects, then I totally understand leaving. If you're leaving because you don't want to maintain a system that's "older" and don't want to take on the challenge of improving it then I agree with your post. I'd rather not have those developers to begin with.
