Dems were elected to undo damage. They chose not to because their platform is higher taxes on corporations and high earners, and ended up creating the tech downturn on their watch. Republicans came in and immediately reversed it with zero Democrats support.
Both sides are the same, Republicans destroy things and Democrats are not perfect in stopping and fixing them! "I am gonna support Republicans as they create problems and then blame Democrats" just makes you someone who intentionally creates problems.
Dems had the chance to fix it and intentionally did not. Republicans did it immediately once they had the chance. If Dems weren't elected in 2020 we'd have plenty of tech jobs now. Their fault, full stop. If Kamala was elected, her platform was even higher corporate taxes.
