Part of this is misconception of the past, see Ecclesiastes 7:10
>10 Say not thou, What is the cause that the former days were better than these? for thou dost not inquire wisely concerning this.
Another part is the fact that the latter days actually are upon us. However, it's not like there has ever been a "golden age" since the time of the fall in Genesis chapter 3. We just choose to focus on what seemed to be better about those times while missing the larger picture, that there is no new thing under the sun. Not until the Savior's return, to right everything that is wrong, will this be resolved. Armed with knowledge of the coming glory of God, we are to be a light in the world (Matthew 5:16) rather than being cynical, as it says in 2 Peter,
>3 Knowing this first, that there shall come in the last days scoffers, walking after their own lusts,
>4 And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation.
>5 For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water:
>6 Whereby the world that then was, being overflowed with water, perished:
>7 But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
>8 But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.
>9 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
>10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
>11 Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness,
>12 Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?
