The expansion of unitary executive power has been the worst development in the US IMO and it opens the door to corruption. Biden overextended his power a number of times, Trump now does it far more than his first term and started doing it as a matter of policy. If you follow SC rulings it's obvious both ends of the SC support that expansion in different ways, often on partisan grounds rather than a consistent concept of separation of powers. Which is the worst part.

Best way to avoid this is having a competent congress, one that actually responds to public concerns so it's not forced upon the president. Which is always the root cause of all of this bad policy from the WH getting shut down by courts or risky incomplete policy being ignored by the courts for the greater good (like abortion rights never becoming a hard law through congress).
