I was in exactly the same situation 4 months ago OP. DC1 was induced, and the epidural was in place before the drip went in. The whole process was smooth, controlled and well managed. I have an existing health condition and the concern was natural labour could be very difficult for me.
For DC2, I went into spontaneous labour the day before my induction was booked. I had requested the same again and had a big sticker on my notes that I was high priority for the anaesthetist. Unfortunately there was an emergency and I spent 4 hours in labour on just gas and air. Epidural finally arrived about 3 am and from then everything went smoothly. But all I can remember is those hours of sheer panic and pain.
I felt there was a similar attitude from the midwife to those displayed here - women do this all the time, get on with it. I didn't feel at all supported, I was terrified and I think about it every day, five months on. I don't think there was a conspiracy to withhold pain relief, just that in my case I really needed someone to help me understand what I was going through, as even though I had given birth before this was all new to me and I don't feel the midwife did this. She did her job, she delivered the baby, but I am still struggling with it all. Also didn't help being told that in the final stages when I tore quite badly that it wouldn't have happened if I had been breathing properly. 
Also I don't think my notes were read clearly. After the birth I just wanted to go home, but was told I couldn't until I had had a shower "to show the epidural had worn off". Midwife helped me to the shower door then left. Went in, just a normal shower. I'm a wheelchair user, I can walk short distances but not stand for any period of time so those showers are difficult at the best of times. So had to sit on the floor, then find my own way back to the delivery suite without any of my mobility aids
. It is very obvious from my notes I am disabled, and my wheelchair was there in the delivery suite!
Yet with DC1 the midwives (I was kept in for a week, there were many!) were all amazing.
