Though Pearce's side went to Israel with high hopes, they ultimately flopped, failing to win a game as they crashed out at the group stage.
Pearce estimated he had been without 17 players, eight of them with senior caps, for the tournament. He specifically named Manchester United duo Danny Welbeck and Phil Jones, plus Arsenal's Alex Oxlade-Chamberlain, who all went to Brazil for England's senior friendly at the beginning of June instead.
Asked whether he regretted the move, Hodgson said: "No. Under-21 tournaments are for the development of players.
"I defy people to name the last four winners of the Under-21 and Under-20 Championships.
"Don't suddenly start suggesting if we don't win these tournament we are hopeless.
"A lot of the players, who are good at the age of 21 are helping the senior team. That is what counts above all.
"Gary Neville played God knows how many games for the England at senior level but never played one Under-21 game.
"When you are not the senior team manager your job is to provide players for the senior team."
Hodgson also defended the performances of both the Under-21s and their Under-20 counterparts, who left Turkey having made a similarly woeful impact, extending an unhappy record of not winning a World Cup finals game at that level in 16 years.
"Before people start extrapolating major conclusions, they should have studied those games a little bit more and taken a damn sight more interest before they got to the tournament.
"I don't remember a word being written or anything being discussed about them beforehand. And I don't see too many people saying Germany and Italy didn't qualify for the Under-20s and France weren't in either of them."
Pearce's answer would be to leave all players in their own age groups until there was no further avenue for them other than the senior side.
It seems highly unlikely the Football Association would sanction such a move, and whilst Hodgson claimed he would accept the situation if they did, he pointed out it would go against everything it has done in the past.
"It is an idea," he said.
"There are a lot of things going on now with Dan Ashworth coming in as technical director and a new Under-21 manager.
"We are looking for a very clear line coming down from the Under-21s, through the 19s and the 17s. Then it will be up to the Football Association to decide.
"If they want to do that, fine. But it would go against everything we have ever done in the past.
"I have never seen an England team choose players to win an Under-21 tournament and not use them in the senior team.
"It would be breaking a mould."
