Yeah. My observation on this is that the more conservative party takes power when there is already an economic boom and takes all the credit for it. Then, once they ruin everything, the liberal side has to step in and repair all the damage.

There seems to be this fundamental problem with democracy that when times are good, people don't want to pay taxes, and they vote in the party that promises to lower them. But then when the economy tanks, they want that safety net again. It's an interesting thought experiment as to what would happen if you had it the other way? So while times are good, you raised the taxes so that the government would have a cushion to weather the next economic downturn and help everyone back on their feet.
