Comfortable dress shirts and ties do exist.
I disagree, at least for off-the-rack clothes. I have a 17.5" neck, and looking at me you wouldn't think I'm a no-neck football player. When I get a fitted shirt that is correct for my neck, it means that I've got to fold in at least 4" extra fabric around my waist. It seems that all clothes here in America assumes that some people are obese, and the rest of the population is merely fat.
I think the only way to get a dress shirt that's anywhere near the right size is to have it tailor-made.
