Not being funny, gentlemen, but let's get very specific here. You say
"you have to be filthy rich or your parents have to be have very deep pockets to get into any of these so called "sponsorship" schemes. It gives the normal person no chance of taking any of these opportunities!"
But what you actually mean is "you have to be filthy rich or your parents have to have very deep pockets to get onto one of these schemes without actually having to work for it yourself first".
There is absolutely nothing stopping you working for x many years to save the money to be able to pay for it yourself. Indeed one of the last batch of TC cadets to be accepted (And now flying the 757 for them) did exactly this. The ONLY thing stopping this approach, is you yourself. Have some pride and go and EARN the right to train, rather than spending someone elses money to do it.
To moan that you can't get the loan for this and that ends any hope you have of applying for it says very little of your commitment to it.
In response to the original point, no, it's not fair. Welcome to life.
