Comparing Diniz to (say) Inoue, he stands head and shoulders above his peers. He may never be a championship contender but he can drive competitively. He's not far away from Salo on pace. His current employment is based on ability not money. Mazzacane is pretty poor quality, and closer to Enemy Ace's opinion.
However, without these pay drivers there would be fewer teams. Jordan did it and pulled itself away from the bottom of the grid. Minardi are trying to do the same.
If we stop pay drivers or drivers of a lesser quality than Mickey-the Shoe we'd only have one car on the circuit. Then who would M-t-S blame when he spun off!!!
