H2Z, I empathise somewhat with your position but feel you may be missing the point. Tax is mandatory. You don't have the discretion to pick your tax liability to whom ever based on your own moral code, no matter how well intentioned you may be.
When mol announces he will base 2 aircraft someplace generating X number of jobs, he is lauded by local government. Fr has set up a system which "socially dumps" services, often on our poorest European and now North African nations. The brilliance of the scheme is that you carry the can and while he gains the commercial advantage with below market rates, you underwrite his operation.
Your going home for dentistry was commendable dragging as you were all your rubbish of the last 5 days (hand luggage was it? ). But you got to the airport on roads, if your hotel accommodation caught fire were you going to call the local lads, or sit tight and await the cavalry from home? In an emergency would you really have refused medical assistance locally and dragged your crippled carcass back home? All services were available and required paying for but FR opted you out of your social responsibility, I can of course understand yours and others rationalisation of the abuse of the system but suspect deep down you know you're being played.
