Cost of PC/Equipment has no bearing on ability to drive.
However, people that are more 'involved' with LFS tend to devote a large portion of their disposable income to their preferred hobby, namely the computer. Therefore it is only natural that you find people that are classed as aliens tend to have (statistically speaking) better set-ups.
Point I am making is that if somebody consecrates a lot of time to practice, then they will soon wear out 'normal' wheels, and will need a wheel with more durability, which just happens to cost a heck of a lot more pennies. (G25: €200, ECCI setup: €1800!!!!)
Furthermore, if they spend 6 hours a day or more at the screen, then they are going to want a very good image to look at...all this costs money..
Big question is, what comes first? Chicken or the Egg?...Alien or Ninja PC?
