GotQuestions often has Biblical answers to common questions. It has supporting data for this one:

I'll also add that the Bible teaches that Satan puts thoughts in people's heads, including rulers and business elites, to cause them to pr p mote his goals. If true, we will repeatedly see the same ideas pop up that the Bible warns about pushed top-down in many cultures. We'll also see them do damage over time.
So, in Revelation, it's a push for world governemnt, a single currency, and ability of governments to dictate both commerce and religion (esp universalism). In Old Testament, the pagans push subjectivism (eg polytheism/atheism), sexual immorality (esp homosexuality), exploitation of the poor, arrogant attitudes, violence, and sacrificing infants for more sex or money.
If we see these trends, we're to oppose them because God promises to punish them in Leviticus and Deuteronomy. Historical data confirms that most countries that did such things were destroyed in time. Often from the activities driven by their cultures. That's also why we not only share Christ and His Word but promote character education and righteous government.
(Note: Christians being mere humans beings redeemed from sin, but with a human nature, means they will often fall short of the above goals in politics and life in general. Sadly. Doesn't make it any less true, though.)
