第二篇 Employment Opinion polls are now beginning to show an unwilling general agreement that, whoever is to blame and whatever happens from now on, high unemployment is probably here to stay. This means we shall have to find ways of sharing the available employment more widely. But we need to go further. We must ask some fundamental questions about the future of work. Should we continue to treat employment as the norm Should we not create conditions in which many of us can work for ourselves, rather than for an employer Should we not aim to revive the household and the neighbourhood, as well as the factory and the office, as centres of production and work The industrial age has been the only period of human history in which most people’s work has taken the form of jobs. The industrial age may now be coming to an end, and some of the changes in work patterns which it brought about may have to be reversed. This seems a discouraging thought. But, in fact, it could offer the prospect of a better future for work. Universal employment, as its history shows, has not meant economic freedom. Employment became widespread when the enclosures of the 17th and 18th centuries made many people dependent on paid work by depriving them of the use of the land, and thus of the means to provide a living for themselves. Then the factory system destroyed the cottage industries and removed work from people’s homes.

All this may now have to change. The time has certainly come to switch some effort and resources away from the impractical goal of creating jobs for all, to the urgent practical task of helping many people to manage without full-time jobs. The passage tells us that the arrival of the industrial age meant that______.
胡某系某单位工程师，1996年因老伴去世而导致精神失常。胡某曾因有过发明创造而获得了不少的收入，因而拥有支票账户。1997年4月5日胡某签了一张20万元的转账支票给某家具制造厂订做一套名贵家具。因支票的出票人系个人，某家具制造厂提出应有保证人进行保证。胡某找到其朋友高某(以单独立户)作为保证人提供了保证担保。家具制造厂收到支票后在4月8日以背书的方式将该支票转让给甲木材公司以支付所欠的木材货款。4月12日甲木材公司持该支票向某百货公司购置机器10台，4月16日某百货公司通过其开户银行提出付款时，开户银行以超过提示付款期为由作了退票处理。百货公司只好通知其前手进行追索。在追索过程中，甲木材公司和家具制造厂均以有保证人为由推卸自己的责任，保证人高某则以胡某系精神病人、其签发的票据无效为由而拒不承担责任。经鉴定，胡某确系精神病人，属于无行为能力人。 请问： 甲木材公司和家具厂推卸票据责任的理由是否合法为什么
