Here's some reality: since 1981, just about every economic measure available has gotten worse. The election of Reagan brought us the "conservative era;" and as the following measures show, it has been a damn catastrophe for the nation and its middle class (the top 10% excluded, who have done exceedingly well since then, which is not mere coincidence).
The only measure that has improved, at least nominally, is the stock market. The stock market is of course almost entirely owned by the wealthy, so this uptrend mainly benefits them. And of course even this increase was primarily financed on the backs of the middle class, through the cannibalization of our productivity and the piracy of our affluence, and later through taxpayer-backed cheap money for the backs, followed of course by taxpayer-financed bailouts of the banks. Upwards wealth transfers, all of it.
Here's a simple fact: Reagan massively increased the spending of our government - an inconvenient core truth about the alleged "small government" hero's governance. But he also sat astride the apex of American power and wealth - the nation's downtrend slide can almost entirely be traced back to its genesis during Reagan's tenure (except a few areas of decline that began under Nixon).
The myths and lies and treasons of Reagan are almost too numerous to list. But it is worth reiterating that he launched an explicitly illegal war in Nicaragua in violation of an explicit law of Congress, which he did by supporting drug-running death-squad terrorists who were overthrowing a democratically elected government and torturing and killing a lot of civilians in the process, He illegally sold missiles and other weapons to Iranian terrorists in order to pay for the illegal war in a massive secret money laundering scheme, and he lied about all of it to Congress and to the people. The entire scheme was swept under the rug when his former Vice President pardoned the gang of conspirators with preemptive, prejudicial amnesty - a get-out-of-jail card card that was granted before the trials even began. Reagan's covert support of Saddam Hussein is another area of disgrace.
Reagan also "blinked" in the face of terrorist demands, when he bribed Iranian terrorists with weapons (and a cake) to gain the release of their hostages, this is a betrayal that his predecessor Jimmy Carter refused to make.
Oh, Reagan also raised taxes several times - on the middle class. But his biggest betrayal of the nation was that he initiated the destruction of the middle class. The numbers speak for themselves....
Some things that got worse since 1981...
The National Debt
(Debt goes parabolic in 1982, second spike in 2003)
Balance of Trade
(Trade balance declines beginning in 1981, crosses axis from surplus to deficit in 1986; then the decline spikes downward in 2000)
(Employment peaks just before 1980; falls off a cliff in 2001)
(To be fair, the manufacturing share of GDP started to decline long before 1981)
Labor's Share of Productivity Gains
(The productivity-wage divergence trend spikes in 1983)
(Rate of growth peaks in 1982)
(Savings rate peaks in 1982 and then falls off a cliff)
(First parabolic move up is in 1982; second in 2000)
(Income growth diverges in 1979; goes parabolic in 1984)
Income Share of the Top 10% Diverges about 1981 (aka the "great divergence" after 40 years of middle class prosperity)
"Financialization" of the Economy
(Converting the economy from one that made things to one where the financial sector made money as middlemen, without adding much value, while everyone else went into debt. This change starts between 1981 and 1984, with debt going parabolic in 2002)
