Absolutely, but it actually does more than that, the high barriers to entry
and high cost to remain have three effects:

1. Only large monopoly CAs tend to prosper (government- and corporate-backed
vanity CAs with independent funding are another matter, but then they only
issue vanity certs so barely count).

2. Everyone becomes a reseller for a CA (with minimal controls and checks and
balances) rather than a full CA (with audits and checks and balances).

3. Because of this there's an impenetrable mass of cross-certifications of
sub-CAs that make it more or less impossible to determine whether you've ever
managed to knock out a rogue player.

In effect the Web PKI selects for the worst possible type of PKI.
