Think of all the opportunities to hold desperate people as hostages in order to bring in votes for a "Party of Yes." Think of all the opportunities to then make more people desperate.
When the people find that they can vote themselves money, that will herald the end of the republic. - Ben Franklin
I periodically play the "If I Wanted to Create a Tyrannical Federal Government, I Would ..." game in my mind. Aside from convincing the public to disarm themselves because the danger from themselves was worse than the danger from their rulers, a good one would be to provide more federal help to citizens than their respective states provided (or could provide, if it's deficit spending). I would take more and more of people's paychecks over the years so that there was not much the states could even take to implement their own solutions to the problems, and the resultant bureaucratic waste would eat up so much and give so little for what it took in that there would be pressure for the government to assume complete control, making the states effectively federal districts, with the government eventually considering all income and all wealth within imminent domain for solving the national crisis. To hedge my bets I would accelerate the accumulation of national debt by using a temporary crisis to redefine the "normal" level of spending until confidence in the dollar is lost.
will "unfairly" benefit them. I would use "class warfare" rhetoric to rile people's sense of fairness to raise tax rates on the primary payers and thereby reduce the taxable income. Deficit increases. Blame the bad effects on predecessor's policies, and point out the obvious fact that now the top 10% are paying less (since they are making less of their income taxable) as further unfairness. Soak the rich some more! Keep going until it's Germany before Hitler.
It seems extreme, but sometimes harsh policies are necessary to make a system where no one is better off than anyone else even if everyone is worse off. Progress is fairness, and in Progressivism, Big Brother is here to control things until they become fair, even if that means that Big Brother becomes intrusive in order to make it happen.
