I really need to develop my opinion a little more I think.
I understand where you are coming from in your post against the draft above. True, the top tier of society won't face the same sacrifice as the bottom tier, but I do believe that you'll get a much more representative sample of our population in the military than we currently have right now - and that is vitally important to mobilizing the entirety of America against war on the level of Vietnam protests.
I love my country and I loved the Army. I worked a lot of great people and minus the war the military really did a lot of good for me and my life. It made me the strong confident person I am today (I used to be a fat nerdy kid who played the clarinet in the high school band - no joke).
I'm very against war. I love the opportunity that the modern military gives people and me to move up in the world and there are a lot of valuable life lessons you can learn by going through things like basic training, Airborne school, Ranger school, etc. However, the bottom line is that the military is a tool of war. And, if you aren't prepared to fight in a war, then get the hell out - which is exactly what I did. I'm not going to argue that some wars are justified, but those ones are few and far between. But I think we agree on this.
