This is all true.
It would be a lot more difficult for Republicans to wreck the economy if Democrats actually built a solid economy when they have the chance. Namely, because if Democrats did that, Republicans wouldn't get this much power in the first place. It wasn't the Republicans running the show when the criminal bankers were given trillions in bailout money while millions got kicked out of their homes. It wasn't the Republicans who decided not to prosecute any of the criminal bankers who helped crash the economy a decade ago.
If Democrats are elected into power, fail to represent the people who put them there and represent the oligarchs who run this country instead, then yeah, they share some of the blame when a troglodyte like Trump gets elected and wrecks everything.
People love to talk about how the Democrats help the people but when the banks and shitty ran corporations were on the ropes, who was there to bail them out?
It's a complete joke giving these businesses more money to run when the reason they're going bankrupt is because how they're ran!
That money should have gone to the people, credits for buying new cars, etc. The Government could have taken over people's loans and made it no interest or even bought back houses from people. Those people were victims of predatory lending, the businesses knew those people couldn't pay it back.
They also could have removed the bonuses these higherups gave them selves and even went back a few years and made those fucks pay back every cent back to the company. They should have booted those guys and then found replacements within the company of people who know what they're doing to run stuff.
Instead we got the opposite.
