Not in reality. From 1944 until 1956, and again from 1985 until 1989 the US GDP grew by more than 5%, which is a "booming" economy. Republicans controlled Congress from 1944 until 1956, and the GOP controlled the Senate and the White House from 1984 until 1988, which was preceded by a 25% across the board tax cut in 1983. Even JFK saw an increase in the GDP after a Democrat-controlled Congress gave him his tax cut in 1962. However, the biggest growth in the economy has always been when Republicans have been in charge.
That, however, is changing. Republicans are no longer the "fiscal conservatives" that they once were. In fact, the Republican Party is no longer conservative at all. The GOP stopped being conservative when they stopped passing appropriation bills in 1999 and started passing veto-proof Continuing Resolutions, Omnibus, and Supplemental Spending bills.
The last honest budget, that included all twelve appropriations bills, to pass Congress was in 1998 when Newt Gingrich was still Speaker of the House.
There might be one or two conservatives remaining in Congress, like Sen. Cruz or Rep. Don Young, but they are in a distinct minority.
