You are extremely naive if you think there wouldn't be competition. You think every company will magically decide to not use a single penny of savings instead of trying to hire better employees?
That is pretty big logical fallacy and of course everything can always be misallocated but these tax increases are specifically for specific things so believe what you want.
I have 0 faith in politicians. Unless you change up the political system completely nothing will change. It's a fairy dream to think that Bernie alone can grab billions of dollars more in tax hikes (and getting approved to do so) without owing any favors.
