Then stop arguing with internet strangers and go out and do it yourself. I can't make this any clearer - if you think its unfair, that they take a disproportionate amount, that you work soo much harder, quit bitching and quit. Because I can guarantee you won't - the job security, less responsibility and ability to let someone else worry if you have work or not is far too comfortable. At will works both ways.
~95% of businesses fail in the first 5 years. Have fun.
