sure, some journals have high rejection rates due to high submission rates.
and overall standards of science are becoming stricter
on the other hand, there are more and more journals out there that are looking for papers (I'm not talking about predatory journals, but serious journals, of cours)
This actually tries to strengthen our work especially when we resubmit our work after addressing reviewers' comments. Some reputed journal publish only high quality work. However, there are some predatory journal! be aware of that too.
Publications getting rejected with sufficient justifications has to be accepted. Its due to lack of quality of the research and it cannot be attributed to other reasons.
