One of the second order consequences of progressive taxation is that it increases gross wages for higher earners, as people care about their net pay being larger, not their gross pay. An extreme example, in the UK the tax rate is an effective 60% between £100k and £120k (ish), so people's salaries get driven through that zone quickly. This obviously means there's less money to give to other people.
