More taxes = more power to people who decide how tax system is designed (there are many, many examples where big companies get away with literally not paying taxes)
More money to redistribute = more power to people who decide who will get money and who won't, all those "government investments" are filled with corruption.
Not to mention smaller things like ordering friend's company to create report on how spend tax payer's money, of course the report costs millions of dollars and says nothing.
