Since you can afford to, please go ahead and do it. Make a video of it and post it for us to see. Actually go ahead and start sending in an extra 10% to the government. Don't just talk about it.
Can I afford to send an extra 10%? I already do, as I am in one of the higher tax brackets. I'm already doing more than my part, as I do not use any government paid healthcare - I have to pay for that myself also.
Utilizing the money that I earn for my own family is not greedy, it's practical. Utilizing government money that you did not earn to pay your costs is greedy.
Why are you traveling to the UK to get your teeth worked on? Because it's cheaper? Why don't you just pay a dentist here?
You have already shown that you have no clue about how R&D is funded for technological advances. Do you really think that the UK is the leader in technilogical advances in dentistry?
