In my experience, juniors are absolutely terrified of asking any sort of question at all during a meeting. Senior engineers are far more likely to ask interesting, useful questions.
We hire juniors so that we can offload easy but time-consuming work on them while we focus on more important or more difficult problems. We also expect that juniors will eventually gain the skills to solve the more difficult problems as a result of the experience they gain performing the easy tasks.
If we stop hiring juniors now, then we won't have any good senior engineers in 5-10 years.
Capital gains are risky to generate. Many investments completely fail and when that happens, investors get very little tax relief.
If you increase capital gains tax, the more risky ideas will no longer be viable investment vehicles even though some of them would have been successful. Across the entire economy, the net effect will be less innovation, stagnation, and loss of power relative to foreign countries.
Tax rates are carefully tuned to maximize tax revenue without unduly disincentivizing production. To change them purely based on vibes would be catastrophically stupid.
