Answer 1

Yes.

Śrīmad-Bhāgavatam Mahā-Purāṇa does say that, as do almost all the Purāṇika texts.

ŚB 12.2.3

The Evils of the Kaliyuga

दाम्पत्येऽभिरुचिर्हेतुर्मायैव व्यावहारिके ।
स्त्रीत्वे पुंस्त्वे च हि रतिर्विप्रत्वे सूत्रमेव हि ॥ ३ ॥

3. Mutual liking (and the family pedigree, social status, etc.) will be the criterion of selecting a partner of life, in marriage ; cheating is the order of the day in business relations; satisfaction of the sensual pleasure is the only consideration of the masculine or feminine, and worthiness and wearing of the sacred thread (Yajñopavita) (and not the pious behavior or Vedic or Shastric learning) is the outward index of the Brahminhood.

3. (Personal) liking will be the deciding factor in making the choice of partner in life, and trickery alone will be the motivating forces in business dealing. Capability of affording the sexual delight will be the (only) criterion of the masculine or feminine excellence, and the sacred thread will be the only mark of Brahminhood.
