I'm 6'3" and have many of the same issues. I recognise that things in life are not always going to be fair and that many of these things ultimately even out (we probably save money walking where other take cabs or performing household maintenance shorter people find difficulty).
My bigger concern is the issue for traveling for work, which I do quite frequently. It does seem unfair that in order to not be in miserable pain for hours, taller people must shell out of pocket for doing something that is just part of their job. In fact, I wish airlines actually forced taller people to upgrade. That would make it so that my employer and people inviting me to give talks would be forced to pay for the upgrade to economy plus or business class.
As someone who is fairly but not very tall and who admittedly travels enough to get Economy Plus anyway most of the time, it's hard for me to be too sympathetic beyond a "Yeah, it sucks" kind of way. Airlines do force people who are too wide to upgrade in some way (like buy an extra seat)--though I've had bad experiences when they haven't.
But people want cheaper tickets and companies have their rules. I'm not sure there are good solutions other than negotiate something with your company or shell out the extra cash.
