Matzah is literally free of all additives, externalities and superficial good looks -- it is bread without the hot air.  It represents the bare essentials.

Everything we pursue in life can be divided into necessities and luxuries.  To the extent that a luxury becomes a necessity we lose an element of our freedom by being enslaved to a false need.

Jewish thought teaches that we should not submit to peer pressure, viewing ourselves as competing with others.  It is far better to focus on our "personal bests" rather than "world records"; life is an arena in which we do not need others to lose in order for us to win.

On Passover we can focus on the essence and leave the externalities behind.  It is a time to get rid of the ego that powers our self importance and holds us back through distracting us from our true goals.
