Furuya Sensei believed that Aikido is egalitarian - open to anyone willing to put in the work.
When we think about accomplishment, sometimes we think that only people with super-human like gifts are able to reach the highest pinnacles. Sometimes this is true in that the JFK's of the world with the opportunity, pedigree and prowess are successful.
However, in more times than not, the person who reaches the highest summit is usually just a seemingly average person, but under that ordinary exterior they posses the drive, determination and perseverance to succeed.
Strong, fast, young, athletic, flexible, good-looking or wealthy doesn't get one out of bed nor does it motivate them to go to class especially when they don't want to. The catalyst for success is a mixture of having the drive to go and do something, the determination to do it and the perseverance to keep going in spite of obstacles. Drive, determination and perseverance know no gender, age, athleticism, or socioeconomic background.
We are all the same - we all suffer, are all lonely, are all insecure and we all must put in the work to accomplish something. Aikido is egalitarian because only those seemingly ordinary people who are willing to put themselves out there, put in the work and keep going despite the odds get good.
