Why we get some random non infrastructural things in budget

Why we never get infrastructural projects like research and development institute like south have ,I know that south contribute a good no but wtf up and bihaiye got so much than us even getting a lot money from central social welfare schemes while they don't give a shit to govn as tax , what is difference they have and we haven't in terms of geography,their states beurocrats are more corrupted than ours but still all good projects went to them
