The Australian believes financial concerns are forcing teams to focus on budget rather than talent, and that some of the most worthy drivers are being overlooked.
In what he labelled a 'sad state', Webber believes that has diluted the quality of the current grid to the extent it is actually weaker than it was 13 years ago when he made a home soil debut with Minardi.
"When I was on the grid at the back with Minardi you had Irvine, Salo - all those guys had been on podiums," Webber said.
"The grid was just packed full of guys who had won in F3000, won a lot of impressive races.
"[Now] there are a lot of talented guys out there, but a lot are slipping through the net unfortunately. That's a sad state.
"[Robin] Frijns for example is a phenomenal young talent, [but] has got no cash."
Webber said he remains focused on ensuring protege Mitch Evans reaches F1, but admitted he is wary of the 19-year-old being promoted too early.
Evans won last year's GP3 championship and has taken four podiums for Arden in his maiden GP2 campaign in 2013.
Asked about the example of Sergey Sirotkin, who is set to race for Sauber next year, Webber said entering the sport so young could present a safety concern.
"Maybe it's a safety worry, we'll see," Webber said of drivers being promoted so early.
"You can drive the car, but for sure it's not the optimal point to enter I don't think.
"My job is to get Mitch there to show what he can do, [but] there's not much testing going on at the moment [so] you have to see what they can do in the period they have.
"Is he [Sirotkin] a Kimi or Sebastian? We'll find out."
